  • Recently, we experienced one case of multiple ribs fracture with large chest wall defects. This patient was treated with internal fixation of ribs by use of Judet`s struts and reconstruction of chest wall defects by use of Teflon mesh. Postoperative outcome was satisfactory result and its advantages were reduced duration of operation, prevention of pulmonary herniation and reduced risk of postoperative infection.

  • In an attempt to reduce processing cost and to improve resolution of PDPs, micro mold transfer processing route for barrier ribs of plasma display panel was attempted. In this study, the parameters that may cause defects during the process were identified, which include the shrinkage during UV curing process, stress due to evaporation of organic components, and sintering shrinkage. Considering such parameters, UV curable paste was developed and barrier ribs of PDPs were successfully processed via the process. This work demonstrated the possibility of build-up route in manufacturing barrier ribs of PDP.

  • Barrier ribs in the plasma display panel(PDP) function to maintain the discharge space between the glass plates as well as to prevent optical crosstalk. Patterning of barrier ribs is one of unique processes for making PDP. In this work photosensitive barrier rib pastes were prepared by incorporating binder polymer, solvent, functional monomers photoinitiator, and barrier rib powder of which surface was treated with fumed silica particles. Study on the function of materials for the barrier rib paste were undertaken. After optimization of paste formulation and photolithographic process, it was found that photolithographic patterning of barrier ribs with photosensitive barrier rib green sheet could be used in the fabrication of high resolution PDP.

  • The purpose of this study was to survey the various kinds of cooked beef products focusing on 'Chim' (a steamed beef products) through historical literatures written from 1670 to 1945 in korea. 'Chim' was recorded 25 times in the references and could be classified to 5 groups based on major ingredients such as stomach, intestine, lean meat, tail and ribs. Among the eleven cooked products of 'Chim', 'Kalbi-chim' (a steamed ribs) was recorded most frequently and 'Sundae-chim' (sausage-like product) was the next. Though 'Kalbi-chim' has been used untill present day but 'Sundae-chim' was disappeared in the early 19th centuries. Ribs were most popular ingredient among the major ingredients such as stomach, intestines, lean meat, tail, feet and ribs. Twenty one kinds of subingredients including pheasant meat, blood clot and flour were used for 'Chim'. Decorating ingredients such as roasted sesame power, pine nut and thin-layer fried eggs and seasonings such as pepper, roasted sesame powder, tripe, garlic, soy sauce and seasonings such as pepper, roasted sesame powder, tripe, garlic, soy sauce and sesame oil were used for 'Chim'.

  • In this study, waffle type barrier ribs for counter electrode discharge cells were prepared via micro-molding process. The master mold was prepared by UV lithography and working mold was manufactured by replicating the master mold. The UV paste used in this study consisted of ceramic powders for the barrier ribs, binder, hardener, and dispersant was filled into cavities of a polymeric mold by action of capillary pressure developed between mold and paste. The results demonstrated a possibility of one-step process for the manufacturing of waffle type barrier ribs embedded with sustaining electrodes.

  • To produce a fine structure with uniform surface of barrier ribs in PDP, acid etching process has been used in manufacture process. It is necessary to understand the mechanism of etching, particularly on the interface of ceramic fillers and matrix glass. We investigated the effect of ceramic fillers (ZnO, $Al_2O_3$) on the microstructure of borate glass system to find an etching mechanism of barrier ribs. The barrier ribs was etched with several steps, dissolving a small amount of residual glass, taking out alumina fillers, and removing a cluster type of ZnO fillers and glass matrix.

  • We fabricated flexible electronic paper display(EPD) by using toner particles on plastic (PC) substrate. We observed the relationship between contrast ratio and changes of rib structures. One is a fabrication of ribs on bottom substrate. The display with ribs on bottom substrate had higher contrast ratio about 46% than display with ribs on top substrate. The other is a change of density of rib. The less density of ribs fabricated, the higher the contrast ratio become.

  • In this paper, high precision molding process was developed using a soft mold to fabricate fine closed-types of the barrier ribs for PDP. A green sheet was employed to fabricate the barrier ribs in this process. The soft mold with good demolding characteristics was replicated from a master mold. An optimal forming load which would not fracture the soft mold was also determined. The barrier ribs of rectangular type with upper width of $30\;{\mu}m$ would be fabricated by this process.
