This study was conducted to search solutions to enhance the blood stasis diagnosis pattern differentiation program and improve the quality of Korean Medicine practice training courses by investigating student’s satisfaction using the web version blood stasis diagnosis program which is based on the previously developed blood stasis diagnosis questionnaire and adding criteria for choosing scales and pictures for additional information. During training courses for diagnosing blood stasis, students performed roles of being a doctor and a patient alternately by using the blood stasis diagnosis program as an educational material. Afterwards, students were to answer 11 questions in a Likert 5 scale questionnaire and a short-answer question to investigate the satisfaction of the blood stasis diagnosis program. The average value of 11 questions from the Likert 5 scale questionnaire resulted in a high level of 4.63. The highest ranking questions were questions asking 1) if the blood stasis diagnosis program is appropriate as an educational tool and 2) if the training course was satisfying using the blood stasis diagnosis program. Short-answer questions showed 78.9% positive feedback. Negative opinions such as the complexity of the questionnaire items and the need of additional criteria and visual material were included. The majority of students participating in the survey showed high satisfaction in the diagnosis practice training using the blood stasis diagnosis program. Based on the study, the blood stasis diagnosis program shows sufficient value for practical use if the program UI is improved and certain material is added.

오용택,한용희,한병성,한상철,성태현,홍광준,신동찬 한국전기전자재료학회 2003 전기전자재료학회논문지 Vol.16 No.12

This study investigated the phase transformation of the REBa$_2$Cu$_3$$O_{7-x}$ (RE=Nd, Gd, Dy) superconductor, and CCT (Continuous-Cooling-Transformation) along with the TTT (Time-Temperature-Transformation) diagrams are suggested according to the isothermal and continuous cooling heat-treatments. The peritectic temperature of the 123 phases decreased approximately 3$0^{\circ}C$ when the ionic radius of the rare-earth elements was reduced. The optimum cooling rate where BC and Cu-free phases do not exist was 0.001$^{\circ}C$/s. At this cooling late, the 123 phase grew with a c-axis Perpendicular to the surface and had a well-distributed 211 phase. When the oxygen partial pressure was reduced Outing isothermal heat-treatment, the formation temperature of the 211 phase decreased. In addition, the formation temperature of the 123 phases decreased from 100$0^{\circ}C$ (Nd-123) to 9$25^{\circ}C$ (Gd-123), and finally 875$^{\circ}C$ (Dy-123) according to the decrease in the ionic radius of the tare-earth elements. Compared to Nd-123, Gd- and Dy-123 had a better texture with a well-distributed 211 phase.e.

열처리가 단분산 구형 $SiO_2$ 나노 분말의 자기조립을 통하여 형성된 광자결정 박막의 광특성에 미치는 영향에 대하여 조사하였다. 광밴드갭에 의해 나타나는 반사율 피크는 열처리 온도가 증가함에 따라 단파장 쪽으로 이동하였고, 빛의 회절에 의해 나타나는 Fabry-Perot fringes 피크의 강도도 증가하였다. 또한, 반사율의 절대값도 $250\~300^{\circ}C$ 사이에서 열처리한 시편에서 가장 높은 값을 나타내었다. 미세구조 분석에 따르면 저온열처리를 통하여 입자크기와 결함량이 줄어들고 결정의 치밀도는 증가하였다. We examined the effect of low temperature heat-treatment on the optical properties of the photonic crystals self-assembled using a monodispersed spherical $SiO_2$ nanoparticle. When the heat treatment temperature increased, the reflectance peak, which is induced by the photonic band gap, moved to a shorter wavelength direction, and the peak intensity of Fabry-Perot fringes also increased. The highest reflectance peak intensity was obtained in the sample heat-treated at $250\~300^{\circ}C$. The heat-treatment reduced the average particle size and the quantity of defects, and increased the packing density of the photonic crystal.

오용택,김명순,신동찬,O, Yong-Taeg,Kim, Myung-Soon,Shin, Dong-Chan 한국세라믹학회 2005 한국세라믹학회지 Vol.42 No.7

This study investigated the effects of the substrate and powder content on the fabrication of SiO$_{2}$ photonic crystals by evaporation method. Photonic crystals were self-assembled on quartz, Corning 1737 glass, slide glass, and ITa glass to verify the effects of the wetting angle and surface morphology. The powder contents of the solution were varied from 0.2 to 2.0 wt$\%$. The number of photonic crystal layers increased according to the decrease of wetting angle and surface roughness. The resultant photonic crystals showed the best optical characteristics when the number of photonic crystal layers was within 40 and 50. In addition, the intensity peak of Fabry¡?Perot fringes increased when the wetting angle was large and the particle size was small. Photonic crystals coated on ITO glass showed the highest reflectance peak of 63$\%$ relative intensity.

STUDY ON ANALYSIS OF SIGNIFICANCE OF SYMPTOM-TREATMENT METHOD COMBINATION

오용택,Bo Ryeong Nam,An Na Kim 한국전산응용수학회 2014 Journal of applied mathematics & informatics Vol.32 No.5

Treatment method refers to a principle or method for treating diseases in Traditional Korean Medicine(TKM). As doctors determine the ideal treatment for a patient’s disease or symptom, they are also able to prescribe effective treatment means for the diseases or symptom such as medicinal materials, prescription, acupuncture and moxibustion. Therefore, if significant symptom-treatment method combinations are found from literature or database, proper treatment means for the patient’s diseases or symptom may be presented to TKM doctors and enhanced treatment accuracy and efficiency can be expected. This study aims to analyze the relation between symptom and treatment method by interpreting hypotheses through null hypotheses to find significant symptom-treatment method combinations. This combinations suggested in this study will be compared with TKM experts analysis result to find an objective analysis method and eventually apply the method to medical big data, e.g., a huge amount of literature or treatment records.

전송 부하를 분산하는 무선 센서 네트워크 구축을 위한 TinyOS 기반 LMPR 구현

오용택,정국상,최덕재,김풍혁 한국콘텐츠학회 2006 한국콘텐츠학회논문지 Vol.6 No.12

In Wireless Sensor Network(WSN) a sensor node transfers sensing data to the base-node through multi-hop because of the limited transmission range. Also because of the limited energy of the sensor node, the sensor nodes are required to consume their energy evenly to prolong the lifetime of the network.LMPR is a routing protocol for WSN. LMPR configures the network autonomously based on level which is the depth from the base-node, and distributes the transmission and computation load of the network to each sensor node. This paper implements LMPR on TinyOS and experiments on the performance of LMPR in WSN. As the result, the average of the received rate of LMPR is 91.39% and LMPR distributes the load of the transmission and computation about 4.6 times compare to the shortest cost routing protocol.We expect LMPR evenly distributes the transmission and computation load of the network to each node, and the lifetime of the network will be longer than it used to be. 무선 센서 네트워크의 노드에서 측정된 데이터는 노드의 전송 거리의 제한 때문에 멀티 홉을 통해 베이스 노드에 전송된다. 또한 노드의 에너지가 한정되어 있기 때문에 무선 센서 네트워크의 수명을 연장하기 위해서는 각 노드의 에너지 소모를 가능한 균일하게 하여야 한다. Level based MultiPath Routing(LMPR)은 베이스 노드로 부터의 거리에 해당하는 노드의 레벨을 기반으로 무선 센서 네트워크를 자가 구축하고 데이터 처리 및 전송 부하를 각 센서 노드에 분산시키는 무선 센서 네트워크 라우팅 프로토콜이다. 본 논문에서는 TinyOS 기반으로 LMPR를 구현하고 실험을 통해 무선 센서 네트워크상에서 LMPR의 성능을 측정하였다. 실험 결과 LMPR이 최소 비용 방식으로 선택된 단일 경로로 데이터를 전송하는 프로토콜보다 데이터 처리 및 전송 부하를 약 4.6배 분산시켰다. LMPR을 사용하여 데이터 처리 및 전송 부하를 각 노드에 분산시켜 TinyOS를 기반으로 구성된 무선 센서 네트워크의 수명을 연장시킬 수 있을 것으로 기대한다.
