김홍배,김원일,이승연,Kim, Hong-Bae,Kim, Own-Il,Lee, Seung-Yeon 대한한방소아과학회 2006 대한한방소아과학회지 Vol.20 No.1

We investigated the effect of Sungmagalkun-tang (SGT) on the allergy. We conformed compound 48/80-induced active systemic anaphylatic shock, anti-dinitrophenyl IgE-mediated passive cutaneous anaphylaxis and ovalbumin-induced anaphylatic shock. Also observed IL-4 and GM-CSF mRNA expression in ovalbumin-induced allergic lung tissue and RBL-2H3. Histamine release is measured in RBL-2H3. SGT inhibited active systemic anaphylatic shock, passive cutaneous anaphylaxis and ovalbumin-induced anaphylatic shock by oral administration. We observed that SGT was concentration-dependently reduced IL-4 and GM-CSF mRNA expression in ovalbumin-induced allergic lung tissue and RBL-2H3 by SGT. In addition, SGT reduced histamine release in RBL-2H3. These results indicate that SGT has anti-histamic effect and controls IL-4 and GM-CSF mRNA expression on allergy.

Objectives To evaluate that Okwada affected which factors for treatment of lung fibrosis. Methods Bleomycin induced lung fibrosis model made in mice. After Okwada lyophilized, power sample obtained and melt in distilled water. Okwada solution administered mice through oral route on 21 days after bleomycin instillation and this procedure performed once a day for 7 days. We divided by three groups; normal (control), bleomycin induced lung fibrosis without treatment (experimental), bleomycin induced lung fibrosis with treatment (treatment). On six weeks after bleomycin instillation, mice sacrificed and removed lung. We performed Western blot analysis for TGF-beta, phosphodiesterase 5A, interleukin (4,5,13) and compared therapeutic effects of Okwada. Results On western blot analysis, all normal and experimental mice detected TGF-beta, phosphodiesterase 5A, interleukin 4,5,13. The amount of band of TGF-beta, phosphodiesterase 5A, interleukin 5 in experimental and treatment group was similar. However, interleukin 4,13 of treatment group decreased compared with experimental group. Conclusions Okwada would be effected the lung fibrosis through suppression of interleukin 4,13.

김홍배,손상희,곽계달,Kim, Hong Bae,Son, Sang Hee,Kwack, Kae Dal The Institute of Electronics and Information Engin 1987 전자공학회논문지 Vol.24 No.1

InSb TFT is fabricated by the vacuum evaporation method and I-V characteristics are measured. Employing Davidon Fletcher-Powell algorithm, the device parameters are extracted. The current-voltage relations calculated by extracdted parameters are in good agreement with experimental results. It is found that optimization technique may be more simple and accurate than curve fitting method in device parameters extration.

로버트 벤츄리의 건축에 표현된 양자공존적(兩者共存的) 대입(對立)에 관한 연구 - Mother's House을 중심으로 -

김홍배,이남규,Kim, Hong-Bae,Lee, Nam-Gyu 한국주거학회 2011 한국주거학회 논문집 Vol.22 No.4

This study was conducted to investigate the ambivalent characteristics of dichotomous contradictions expressed by Robert Venturi's architecture. It focused on his Mother's House, which applied his theoretical practices faithfully among many of his architectural works. First, he sought to change interior and exterior spaces by manipulating the architectural scales of "Mother's House". He achieved tension in space through structural complexities in combination with contradictions. Second, as for the characteristics of ambivalent contradictions, including linear and geometric forms, and plane, there were familarity which emphasizes tradition; external appearances of symmetry and asymmetry which give a comfort feeling; openness and closedness, which were expressed with the size of windows and objects such as molding. Third, the fireplace-chimney and the stair were forming appropriate harmony between contradiction and complexity as they competed for central position on the plane.

가상자산 비트코인은 화폐인가, 자산인가?

김홍배 ( Hong-bae Kim ) 한국금융공학회 2020 금융공학연구 Vol.19 No.4

본 연구는 비트코인 수요 관련 국내 데이터의 부재로 실증분석보다는 해외 연구에 기초하여 비트코인의 본질(화폐 vs. 자산)을 검토하였고, 자산 포트폴리오에서 비트코인의 금융자산으로서 기능(투기, 분산, 헤징, 안전자산)에 대해서 살펴보고자 한다. 본 연구의 내용을 정리하면 다음과 같다. 우선, 비트코인에 대한 화폐로서의 위상 부여에 있어서 화폐로서의 기본적 기능 부족을 이유로 화폐로 인정할 수 없다는 연구도 있지만, 향후 비트코인이 화폐로서 발전할 가능성을 제시하는 연구도 다수 있다. 비트코인의 화폐화를 위해서는 지불결제수단으로 채택 확산, 법제도 확립, 국가 간 협정 등의 과제를 두고 있다. 한편, 자산 포트폴리오 관점에서의 첫째, 비트코인을 화폐로서 인정하기를 거부하는 연구들은 비트코인을 높은 변동성을 가진 수익추구의 투기적 자산으로 분류한다. 둘째, 자산 포트폴리오 측면에서 비트코인은 타 자산과의 상관관계에 있어 분산기능을 갖추고 있는 것으로 인식한다. 셋째, 경제 불확실성 지수들이 급변하는 시장변동성에 대해 비트코인이 헤지 기능을 갖는 것으로 인식한다. 마지막으로, 비트코인이 금과 같은 진화과정을 거치고 있지만 금과 같은 안전자산으로서의 기능은 부족한 것으로 나타났다. 이상의 연구결과들을 볼 때 자산으로서 비트코인의 특성은 통화, 원자재, 주식의 금융자산 특성과 상호 배타적이지 않으며, 이러한 특성은 자산 포트폴리오 내에서 분산과 헤지의 다중적 금융자산 기능을 수행할 수 있음을 의미한다. Bitcoin has attracted a lot of attention due mainly to the drastic price surge it has experienced over the last few years. This increase in prices has been accompanied by a huge rise in volatility, which has fueled a debate about the financial nature of Bitcoin. This paper analyzes the demand for Bitcoin in order to shed light on its financial nature of whether it is a currency or an asset. I first scrutinize the economics of Bitcoin from evidencing its shortcomings as a currency to fulfill the functions of money. In addition, I theorize about the possibility of Bitcoin becoming a world reserve currency from the perspectives of macroeconomic stability by comparing with gold standards. In a second part, I perform a theoretical classifications of factors to demand for Bitcoin whether It stems from Bitcoin’s utility as a speculative asset, a safe-haven commodity, or as diversification benefits asset. Bitcoin is not only still in the process of being monetized but It should also be noted that these three categories(currency, commodity and financial asset) are not mutually exclusive. For instance, gold is commodity that was once used as the world reserve currency and is today considered a safe-haven asset by many investors. In the same way, Bitcoin might be perceived and thus employed by investors for different purposes.

보강토교대로 지지된 슬래브교의 설계 활하중에 대한 반력 및 접지압 검토

김홍배(Hong-Bae Kim),한희수(Heui-Soo Han) 한국산학기술학회 2019 한국산학기술학회논문지 Vol.20 No.5

본 연구에서는 보강토교대로 지지된 슬래브교의 설계 활하중을 도로교설계기준(2010)의 DB-24와 도로교설계기준(한계상태설계법)(2015)의 KL-510으로 구조해석을 수행하였다. 구조해석 결과로부터 산정된 슬래브교의 반력과 보강토교대에 작용하는 접지압에 대해 비교검토를 수행하였다. 교대에 작용되는 반력은 교각의 유무와 개수에 따라 다르게 산정되었다. 단경간에 비해 연속교에서 교대에 작용되는 반력이 감소되는 것으로 나타났다. 구조해석 결과, 활하중보다는 고정하중에 의한 반력이 약 2배 이상 크게 산정되었으며, 활하중이 전체 반력에 미치는 영향이 상대적으로 작았다. 보강토교대에 작용하는 접지압은 단경간에서 가장 크게 산정되었다. 이동하중의 종류에 따른 영향은 상대적으로 크지 않았다. 따라서, 연속교에서 교대에 작용되는 반력과 접지압이 작게 산정되기 때문에, 단경간 교량보다는 연속 교량에 보강토교대를 적용하는 것이 유리한 것으로 판단되었다. 보강토교대에 작용되는 반력과 하중 분담률은 다양한 조건에 따라 달라지므로, 다양한 교량 형식과 제원에서의 접지압 검토가 향후 필요하다. In this study, the structural analysis was conducted to the comparison of reaction force and contact pressure on the design truck load (DB-24 and KL-510) of slab bridge supported by MSEW abutment. As a result of the structural analysis, the reaction force acting on the abutment at the continuous bridge was reduced rather than the simple span bridge. The reaction force due to the dead load was estimated to be about twice as large as that of the live load, and the influence of the live load on the total reaction force was relatively small. The contact pressure of the MSEW abutment was estimated to be the largest in the simple span bridge. The influence of contact pressure on the type of live load was relatively small. Therefore, it is considered to be more advantageous to apply the MSEW abutment to the continuous bridge than to the simple span bridge because the contact pressure acting on the abutment on the continuous bridge is estimated to be small. Since the reaction force and the load sharing ratio acting on the MSEW abutment depending on various conditions, it is necessary to examine the contact pressure in various types of bridges and specifications.
