  • 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.

  • 무당개구리 상처치유 과정 중 재생되는 피부 상피세포의 형태학적 특성을 관찰하기 위하여 투과전자현미경을 이용하였다. 상처유도 추 재형성과정 중의 표피는 재생되는 상피세포에 의해 $3\sim4$층을 형성하였으며, 세포들의 크기는 상충에서 하층으로 갈수록 크게 신장되어 있음이 관찰되었다. 세포 간격 또한 세포층의 기저부를 향할수록 넓어졌다. 기저층에 위치한 세포는 세포질 돌기들을 내어 데스모소옴이 형성되어 있었고, 원주형이었다. 기저막이 형성된 세포들 사이에는 원기세포들이 위치하고 있었으며, 이 세포들은 불규칙한 난형 또는 타원형으로 세포의 크기는 다른 세포들에 비해 작게 관찰되었다. 따라서, 상피조직은 재생될 때 원기세포들의 분열과 이동이 동반되어야 하므로, 무당개구리 상피는 시간이 경과함에 따라 정상조직과 동일하게 재생될 수 있을 것으로 생각된다. 본 연구에서 상처가 치유된 시점으로 확인된 31일 경의 상피조직의 관찰 결과 역시 추측했던 점과 일치되어 정상과 동일한 조직학적 구성을 이루고 있었다. 또한 재형성 과정 중 상피는 피부가 정상조직으로 형성되기 전까지 수분유실을 막는 방어벽으로서의 기능과 허물을 벗는데 관여하는 것으로 확인되었다.

  • 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.
