  • United Nations Framework Convention on Climate Change(UNFCCC), an international treaty to prevent the regulation and global warming, has passed through the General Assembly for 17 times from 1992 to 2011. To create a performance plan specific, such as the Kyoto Protocol, it is to promote the reduction of energy consumption and greenhouse gases worldwide. In South Korea, Korea Infrastructure Safety and Technology Corporation(KISTEC) is working and supporting for developing method of green remodeling policy. Among several solutions, "Remodeling" ensures to increase the energy efficiency of buildings and to reduce the emissions of greenhouse gases, and consequently it could maintain buildings high efficiency. For remodeling projects, it is most important to determine construction plan including remodeling scopes and methods, while the plan has been determined by the engineer's background and experience. Therefore, this study aims at developing a method for selecting optimal skin system which has remarkable influence to energy performance of the buildings.

  • This study is a design paper that presents the value of remodeling of aging office building through design plans through outer remodeling of work facilities using Erwin hauer's Design 201 as a form example. Based on the aging of the building, it was judged that the Samsung Main Building, which was completed in 1976, in Jung-gu, Seoul, was possible to remodel the outer shell and prototype. This study used the precast concrete method to analyze Erwin hauer's work to determine spatial potential, and adjusted the opening and size of the module through parameterization considering the construction technology of modern precast concrete, especially UHPC, and computer technology and parametric design methodology. As a result, the design plan is expected to contribute to the creation of brand value as well as to the profit and economic aspect of the office, which can quickly and economically remodel the quantitative increase of old buildings, which was mentioned as the need for outer remodeling. In addition, through the analysis of the works of sculptor Erwin Hauer in the 1950s, his work can be architecturally re-examined due to the development of technology over time, suggesting the possibility of the times that the form has.

  • Remodeling of epithelial cells during wound healing in the skin of the Korean fire-bellied toad, Bombina orientalis, were examined using the scanning and transmission electron microscopical analyses. Artificial wounds were induced on the dorsal surface of the skin by excision, and reared in special cages with normal diets for up to 31 days after injury. From 4 days after wounding, regenerated epithelial cells are more rapidly migrated to wounding area, and remodeling of tissue components are proceeded gradually. Especially, formation of basal lamina between regenerated epithelium and dermis, and reconstruction of cellular junctions such as desmosomes (among the regenerated epithelial cells) and hemidesmosomes (between basal epithelial cells and basal lamina) are detected through fine structural analysis from 10 days after injury. Parakeratosis of regenerated epithelial cells observed during 16 to 19 days after wounding.

  • In remodeling business or construction of both new strucures and existing structures, Case that pile foundation was set is often. Micro pile, holding compressive force and tensile force by spherical friction, is supported by skin friction rather than end bearing capacity. but, This is weak in tension. Active area of micro pile's skin friction is narrow and micro pile don't do unification behavior hence. So bearing capacity was not fully mobilized in existing researching. In this study, in order to compensate for this method, micro pile to install Resisting Fixture is proposed.

  • Background and Objectives High-intensity focused ultrasound (HIFU) can produce small zones of thermal damage. A HIFU procedure is non-invasive and it can achieve rejuvenation of facial skin. Fractional CO2 laser resurfacing delivers thermal damage to the pixilated columnar zone of the skin and so evoke collagen remodeling, the same as HIFU. In many cases, the patients who want rejuvenation with HIFU are also good candidates for cutaneous photorejuvenation such as can be accomplished via fractional CO2 resurfacing. If patients are treated in a single session by remodeling both the superficial and deep compartments of skin by using both modalities, then improvement in rhytides and tightening of sagging skin will optimize the aesthetic result. Materials and Methods Between May 2014 and January 2018, a total of 44 patients were treated with combination HIFU and fractional CO2 laser resurfacing according to our protocol. First, the HIFU was applied to the entire face with an average of 300 treatment lines. Immediately after HIFU treatment, the ultrasound gel was washed off and then fractional CO2 laser resurfacing was performed. We evaluated the patients using 4-point grading scales. The clinician examined the skin for evidence of complications after the completion of treatment. Results All the patients' skin quality showed improvement. Further. the clinical results after duel modality treatment were substantially better than that after the use of either modality alone. The recovery times and the incidence of adverse events when quickly and consecutively performing both treatments were similar as compared to those with employing stepwise treatment. We encountered no complications whatsoever. Conclusion When compared with stepwise therapy, combination therapy with HIFU and fractional CO2 resurfacing offers better, safer and more effective clinical results. Thus, for targeting multiple layers of aging facial skin, this combination therapy can be safely performed in a single treatment session.

  • A needle-free injector is one of the new non-invasive players in impregnating the biological barriers. It is considered as the next phase in drug delivery and therapeutic applications. One of the major fields of application is in skin remodeling procedures. Although many studies were carried out in understanding the principle in the needle-free injection procedure, fewer studies were done with the aim of therapeutic applications. In the present study, we tried to identify key parameters that affect the jet divergence and peak stagnation pressure on the skin surface in a conventional needle-free injector for skin treatment. A summary of the working principle and effect of the key parameters are presented.

  • This study was conducted to investigate the effect of recipient activation time on the nuclear remodeling, chromatin structure, pronuclear formation and in vitro development of bovine nuclear transfer embryos derived from adult ear skin cells. Somatic cells were transferred to enucleated oocytes after quiescent treatments by serum starvation or culture to confluency. Nuclear transfer embryos were activated with a combination of Ca/sup 2+/-ionophore and cycloheximide at 1, 1.5, 2, 2.5, 3, and 5 h after electrofusion. (omitted)

  • We attempted to control the maturation promoting factors (MPF) activity and nuclear remodeling of somatic cell nuclear transfer (NT) bovine embryos. Bovine ear skin fibroblasts were fused to enucleated oocytes treated with either 5 mM caffeine for 2.5 h or 0.5 mM vanadate for 0.5 h and activated. The nuclear remodeling type of the reconstituted embryos was evaluated 1.5 h after activation. MPF activity was assessed in enucleated and chemical treated oocytes before the injection of a donor cell. Effect of chemicals on the embryonic development was evaluated with parthenogenetic embryos. MPF activity increased significantly by caffeine treatment, but decreased by vanadate treatment (p<0.05). Caffeine or vanadate had no deleterious effect on the parthenogenetic embryo development. In caffeine treated group, premature chromosome condensation (PCC) was occurred in 72.2% of NT embryos (p<0.05). In contrast, vanadate induced the formation of a pronucleus-like structure (PN) in a high frequency (68.9%, p<0.05) without PCC (NPCC). Blastocyst development of NT embryos increased by treating with caffeine (30.3%), whereas decreased by treating with vanadate (11.4%) compared to control (22.1%, p<0.05). The results indicate that caffeine or vanadate can control of MPF activity and remodeling type of NT embryos, resulting in the increased or decreased in vitro development.
