        21세기 지식기반 사업을 벤처디자인 전문회사 창업시뮬레이션 연구 : Centering around the Case of the Establishment of a Venture Enterprise, KDI(Kim, Kyung-Hun Design Institute) 벤처기업 KDI(김경훈디자인연구소) 창업 사례를 중심으로

        김경훈 한국비쥬얼디자인학회 1999 한국디자인포럼 Vol.4 No.-

        In the 21st century knowledge-and-information-oriented age, individual diversity is emphasized, and information acquisition and consumption levels are heightened. This trend of the times refuses to accept the mass production system centering around the competition in price. In consequence, inevitably does come the age of value created in which quality goods are produced by the multikind and small quantitiy production system. Design along with information and communication as 21st century knowledge-based business is gaining ground as a main factor national competitiveness is dependent upon in this age. Accordingly, the purpose of this study is to analyze the process and realities of the establishment of a firm specialized in venture design, both one of knowledge-based business and one factor which decides whether in the knowledge-and-information-oriented age, the millennium, our country will gain ground as one of the leading countries in the world or it will set in the west just like the twilight of the 20th century, and try to pave the way to promote the establishment of design venture required by this age. In a knowledge-based economic society, working methods are more important than working hours, and technical knowledge is more important than general knowledge. Desire for self-achievement is to be stronger than unilateral sense of loyalty to an organization. For the country in which there are many men of great originality who can enhance value added through incessant self-improvement, self-development and self -reformation can secure competitiveness among nations in the upcoming century.

        Ni/γ-Al<sub>2</sub>O<sub>3</sub> 촉매상에서 이산화탄소에 의한 프로판의 개질

        김경훈,김종화,장성진,박대원,Kim, K. H.,Kim, J. H.,Chang, S. C.,Park, D. W. 한국공업화학회 1997 공업화학 Vol.8 No.3

        Reforming of propane by carbon dioxide using NiO/${\gamma}$-$A1_2O_3$ was carried out in a pulse or continuous kid bed reactor. NiO/${\gamma}$-$Al_2O_3$ showed higher dissociation ability of $CO_2$ than NiO/${\gamma}$-$Al_2O_3$, and the former exhibited higher conversion of propane than the latter. The presence of oxygen in the reaction mixture of propane and $CO_2$ increased the conversion of propane and reduced the amount of carbon deposit on the catalyst surface. Mechanical mixture catalyst of NiO/${\gamma}$-$Al_2O_3$ and $Ga_2O_3$ showed higher stability to deactivation than NiO/${\gamma}$-$Al_2O_3$ itself. The synergistic effect between NiO/${\gamma}$-$Al_2O_3$ and $Al_2O_3$ was also observed in this study. 본 연구는 펄스 반응기 및 고정층 연속반응기를 사용하여 ${\gamma}$-알루미나에 담지된 니켈촉매상에서 이산화탄소에 의한 프로판의 개질반응 특성을 고찰한 것이다 Ni/${\gamma}$-$A1_2O_3$촉매가 NiO/${\gamma}$-$A1_2O_3$촉매보다 $CO_2$의 해리능력과 프로판의 개질 능력이 우수한 것으로 나타났다. 프로판과 $CO_2$의 혼합물에 산소를 추가한 결과 프로판의 전환율이 증가하였고 표면의 탄소침적도 감소함을 알 수 있었다. Ni/${\gamma}$-$A1_2O_3$와 $Ga_2O_3$의 기계적 혼합 촉매는 Ni/${\gamma}$-$A1_2O_3$자체보다 촉매의 활성이 오래 유지되었고 두 상의 협동에 의한 상승효과(synergistic effect)가 관찰되었다.

        해방 전 설인 시세계 연구

        김경훈 한국문학치료학회 2012 문학치료연구 Vol.22 No.-

        Seo Rin is one of representative Korean poets in China, whose writing accompanied the complicated phases of times from before liberation to after liberation. The process of his creative writing also means the history of change in Korean poetry. Seo Rin's works were attractive enough to catch the readers owing to various themes and distinctive expressions. Although it's not easy how his works were embellished after liberation, his works excellently expressed national reality and conflicts in a poetic way. His works showed indirectly the literary trends of Korean poetry those days by way of centering around images such as "water", and "night", and of using unique tone and poetic language. 설인 시인은 조선족의 대표적인 시인 중 한 사람으로, 그의 창작은 해방 전에서 해방 후에 이르는 복잡한 시대상과 함께 하며, 그 창작 과정 자체가 조선족 시가사의 변천사를 의미하기도 한다. 설인 시인의 해방 전 작품은 비교적 다양한 주제와 특징적인 표현으로 읽는 이의 눈길을 빼앗기 충분하였다. 비록 해방 이후에 어느 정도 윤색이 되었는지를 파악하기 쉽지 않으나 대체로 민족의 현실적 모순과 갈등을 시적으로 잘 그려내고 있었고 ‘물’과 ‘밤’과 같은 이미지를 중심으로 특이한 어조와 시어에 의해 해당 시기 조선족 시 문단의 맥락을 측면적으로 잘 보여주고 있었다고 판단된다.

        Mechanical Antiallodynic Effect of Intrathecal Nefopam in a Rat Neuropathic Pain Model

        김경훈,변경조,김희영,백승훈,신상욱,구성태 대한의학회 2015 Journal of Korean medical science Vol.30 No.8

        Nefopam has a pharmacologic profile distinct from that of opioids or other antiinflammatory drugs. Several recent studies demonstrate that nefopam has a mechanism of action similar to those of anti-depressants and anticonvulsants for treating neuropathic pain. The present study investigates the mechanical antiallodynic effect of nefopam using immunohistochemical study and western blot analysis in a rat neuropathic pain model. Twenty-eight male Sprague-Dawley rats were subjected to left fifth lumbar (L5) spinal nerve ligation and intrathecal catheter implantation, procedures which were not performed on the 7 male Sprague-Dawley rats in the sham surgery group (group S). Nefopam, either 10 or 100 μg/kg (group N10 or N100, respectively), and normal saline (group C) were intrathecally administered into the catheter every day for 14 days. The mechanical allodynic threshold of intrathecal nefopam was measured using a dynamic plantar aesthesiometer. Immunohistochemistry targeting cluster of differentiation molecule 11b (CD11b) and glial fibrillary acidic protein (GFAP) was performed on the harvested spinal cord at the level of L5. Extracellular signal-regulated kinase 1/2 (ERK 1/2) and cyclic adenosine monophosphate response element binding protein (CREB) were measured using western blot analysis. The N10 and N100 groups showed improved mechanical allodynic threshold, reduced CD11b and GFAP expression, and attenuated ERK 1/2 and CREB in the affected L5 spinal cord. In conclusion, intrathecal nefopam reduced mechanical allodynia in a rat neuropathic pain model. Its mechanical antiallodynic effect is associated with inhibition of glial activation and suppression of the transcription factors’ mitogen-activated protein kinases in the spinal cord.

        Low Grade Pulmonary Lymphomatoid Granulomatosis with an Endobronchial Mass

        김경훈,박진희,유지연,김민재,김일,이진국,이혜연 대한결핵및호흡기학회 2015 Tuberculosis and Respiratory Diseases Vol.78 No.2

        Lymphomatoid granulomatosis (LYG) is an angiocentric and angiodestructive neoplastic proliferation of B and T lymphocytes commonly involving the lungs. Epstein-Barr virus is commonly detected in lesional cells. We report a case of a 54-year-old female with underlying monoclonal gammopathy of unknown significance who presented with a 4 week history of dyspnea and cough. Computed tomography scan of the chest showed multiple lung nodules as well as endobronchial narrowing causing atelectasis at the left upper lobe. Bronchoscopic findings revealed obstruction at the lingula segment due to endobronchial mass as a rare presentation. Bronchoscopic biopsy was diagnosed with LYG grade 1. After treatment, the endobronchial mass and lung lesions were completely resolved. However, the patient eventually evolved to malignant lymphoma after 1 year.

        김경훈,유재하,이춘수 한국통상정보학회 2014 통상정보연구 Vol.16 No.3

        '스콜라' 이용 시 소속기관이 구독 중이 아닌 경우, 오후 4시부터 익일 오전 9시까지 원문보기가 가능합니다.

        Medical tourism involves patients intentionally leaving their home country to access non-emergency health care services abroad. Growth in the popularity of this practice has resulted in a significant amount of attention being given to it from researchers, policy-makers, and the media. Yet, there has been little effort to systematically synthesize what is known about the effects of this phenomenon and key choice factors. This study seeks to figure out, using conjoint analysis, what factors Chinese medical tourists place importance on maximizing utility when selecting their destination and propose selection attributes that can lure medical tourists to Korea. Results showed that, of destination attributes, medical technology competitiveness proved be the most important and of lower levels, international accreditation proved to have the highest utility. This article presents the findings of valuable insights to medical institutions, travel agencies and related firms in their marketing activities.

        Improved Circuits for Single-photon Avalanche Photodiode Detectors

        김경훈,이준안,송봉섭,범진욱 대한전자공학회 2014 Journal of semiconductor technology and science Vol.14 No.6

        A CMOS photo detection bias quenching circuit is developed to be used with single photon avalanche photodiodes (SPADs) operating in Geiger mode for the detection of weak optical signals. The proposed bias quenching circuits for the performance improvement reduce the circuit size as well as improve the performance of the quenching operation. They are fabricated in a 0.18-μm standard CMOS technology to verify the effectiveness of this technique with the chip area of only 300 μm2, which is about 60 % of the previous reported circuit. Two types of proposed circuits with resistive and capacitive load demonstrated improved performance of reduced quenching time. With a commercial APD by HAMAMATSU, the dead time can be adjusted as small as 50 ns.
