This study investigated the influence relationship of information service using QR code on customer's service quality perception and loyalty behavior for medical service in the physical environment. As a result of the study, when medical institutions provide location information services about the physical environment by utilizing the usefulness and reliability of QR codes, the perceived quality of customers' QR information will be strengthened, and furthermore, loyalty behavior toward medical services will increase in the future. Considering the spread of smartphones as a popular digital medium today, marketers use QR codes to connect and provide four-dimensional information services without time and place restrictions, thereby strengthening the interactive experience with customers. And these efforts suggest that it can contribute to improving service image and strengthening loyalty beyond simply providing service information to companies.

김미라,이성대,채연식,이진구,Kim, Mi-Ra,Lee, Seong-Dae,Chae, Yeon-Sik,Rhee, Jin-Koo 대한전자공학회 2007 電子工學會論文誌-SD (Semiconductor and devices) Vol.44 No.8

We designed and fabricated the planar graded-gap injector GaAs Gm diodes with $1.6{\mu}m$ active length for operation at 94 GHz. The fabrication of the Gunn diode is based on MESA etching, Ohmic metalization, and overlay metalization. The measured negative resistance characteristics of the graded-gap injector GaAs Gunn diodes are examined for two different device structures changing the distance between the cathode and the anode electrodes. Also, we discuss the DC results under the forward and the reverse biases concerning the role of the graded-gap injector. It is shown that the structure having the shorter distance between the cathode and the anode electrode has higher peak current, higher breakdown voltage, and lower threshold voltage than those of the larger distance. [ $1.6{\mu}m$ ]의 활성층을 가지는 planar형태의 94 GHz graded-gap injector GaAs 건 다이오드를 설계, 제작하였다. 이 다이오드는 반 절연 기판에 성장된 에피 구조를 바탕으로 메사 식각, 오믹 금속 접촉형성 및 overlay metalization의 주요 공정을 통하여 두가지 형태의 planar 구조로 제작되었다. 제작된 건 다이오드의 부성저항 특성을 anode와 cathode 금속전극들의 배치를 달리 한 두 소자 구조에서 고찰하였고 graded-gap injector의 역할을 순방향과 역방향에서의 직류거동으로부터 살펴보았다. 결과적으로, 금속전극의 배치에 있어서, cathode와 anode 전극사이의 거리가 감소된 소자 구조에서 증가된 peak 전류와 breakdown 전압, 그리고 감소된 문턱전압을 얻었다.

Tumor Necrosis factor-α Promotes Osteogenesis of Human Bone Marrow-derived Mesenchymal Stem Cells through JNK-dependent Pathway

김미라,송해영,김재호,Kim, Mi-Ra,Song, Hae-Young,Kim, Jae-Ho Korean Society of Life Science 2006 생명과학회지 Vol.16 No.7

Tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$는 염증성 골질환에서의 골조직의 손실과 밀접한 관련이 있다. 본 연구에서는 인체 골수 유래 중간엽 줄기세포의 골세포로의 분화과정에 대한 $TNF-{\alpha}$의 영향을 조사하였다. $TNF-{\alpha}$는 골수 유래 중간엽 줄기세포의 골세포로의 분화를 나타내는 표시인 세포외 무기질 축적과 alkaline phosphatase의 발현의 증가를 일으켰으며 2ng/ml의 농도에서 최대의 증가를 나타내었다. $TNF-{\alpha}$에 의한 골세포로의 분화는 $NF_kB$의 저해제에 의해서는 영향받지 않았으나 JNK 특이 저해제인 SP600125에 의해 완벽하게 억제되었다. 이는 $TNF-{\alpha}$에 의한 골수 유래 중간엽 줄기세포의 골세포로의 분화과정에 JNK가 중요한 역할을 한다는 것을 제시한다. Tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$ has been implicated in skeletal diseases by promoting bone loss in inflammatory bone diseases. In the present study, we examined the effects of $TNF-{\alpha}$ on osteoblastic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs). $TNF-{\alpha}$ dose-dependently promoted matrix mineralization of hBMSCs with a maximal stimulation at 2ng/ml. $TNF-{\alpha}$ increased expression of alkaline phosphatase, which plays a crucial role for the matrix deposition. The $TNF-{\alpha}-stimulated$ osteoblastic differentiation was not affected by $NF_kB$ inhibitors, BAY and SN50. However, a JNK-specific inhibitor, SP600125 completely abolished the $TNF-{\alpha}-stimulated$ matrix mineralization and expression of alkaline phosphatase. These results suggest that $TNF-{\alpha}$ enhances osteoblastic differentiation of hBMSCs through JNK-dependent pathway.

우슬 중 ${\beta}-Ecdysone$의 초임계추출법(SFE)과 용매추출법의 비교

김미라,김명석,심재한,Kim, Mi-Ra,Kim, Myong-Seok,Shim, Jae-Han 한국응용생명화학회 2001 Applied Biological Chemistry (Appl Biol Chem) Vol.44 No.3

우슬(Achyranthis radix)중 ${\beta}-ecdysone$의 초임계추출법과 용매추출법의 비교를 위해 초임계유체추출(SFE) 및 용매추출 후 초임계유체크로마토그래피(SFC)에 의한 우슬 중 ${\beta}-ecdysone$ 분석을 실시하였다. SFE에 있어서 추출 최적압력은 300 atm이었으며, 온도는 $80^{\circ}C$, 추출량은 100 ml, 보조제인 methanol 함량비율은 20%였다. 우슬에서 ${\beta}-ecdysone$의 분석시 SFC의 최소검출량은 5 ng이었고, SFE의 회수율은 줄기에서는 $90.7{\sim}93.5%$였으며, 뿌리에서는 $77.8{\sim}81.9%$였다. 용매추출의 회수율은 줄기에서는 $76.4{\sim}93.0%$였고 뿌리에서는 $80.6{\sim}93.1%$였다. 우슬의 생육기별 조사에서 ${\beta}-ecdysone$은 주로 뿌리에서 많이 검출되었고 1년생이면서 8월에 수확한 것이 654.9 ppm으로 가장 많이 함유한 것으로 나타났다. Extraction efficiency of ${\beta}-ecdysone$ in Achyranthis radix was investigated using the methods of solvent extraction and supercritical fluid extraction (SFE). The optimum SFE conditions for the analysis of ${\beta}-ecdysone$ in A. radix were 300 atm, $80^{\circ}C$, 100 ml of extraction volume, and 20% ratio of modifier(methanol). As revealed through SFE, detection limit of ${\beta}-ecdysone$ in A. radix was 5 ng and recoveries of ${\beta}-ecdysone$ in A. radix shoots and root were $90.7{\sim}93.5%$ and $77.8{\sim}81.9%$, respectively. Recoveries of ${\beta}-ecdysone$ in A. radix shoots and root through solvent extraction were $76.4{\sim}93.0%$ and $80.6{\sim}93.1%$, respectively. ${\beta}-Ecdysone$ content was determined to be highest at 654.9 ppm in the first year A. radix roots harvested in August.

This author deems that pathological phenomena existing all around our society today have basically resulted from the loss of character education in childhood. This study is aimed to seek ways to solve the problems with the righteous methodology of early childhood education applied by head family that has preserved and transmitted traditional living culture. Believing that they have handed down ancestors’ mind and culture to descendants for the last 500 or so years, they have followed and succeeded to the values preserving and protecting their old house. This researcher has explored the living culture of Korea’s prestigious head family and examined their methods and contents of early childhood education profoundly. First of all, considering the character and character education found in Confucian scriptures, this research examined the contents and methods of character education according to the process of child growth. Second, this author investigated character education for children explored in the living culture of three head families out of Andong head families: Daesan Lee Sang-jeong head family, Sujeongjae Ryu Jeong-mun head family, and Hakbong Kim Seong-il head family. Third, within the living culture of the 21st-century Ongojisin (溫故知新; review the old and learn the new) head families, this author drew character education programs for children. Consequently, this researcher has found that those head families’ early childhood education can be reapplied and reused newly in the field of contemporary family education.
