Objective： To evaluate the consistency of patterns and pattern identification（PI）, and the improvement in the diagnosis of blood stasis after the standard operating procedures（SOPs） were enhanced by using a diagnostic flowchart. Methods： A total of 358 subjects who were admitted by the Jaseng Hospital of Korean Medicine between June 2013 and December 2014 were included in the study. Each patient was independently diagnosed by two experts from the same department. In 2014, the SOPs included the use of a diagnostic flowchart for each indicator. Inter-observer consistency was assessed by simple percent agreement and by the kappa and AC1 statistics. Results： The improvements in inter-observer agreement for the indicators（for al patients） and PI were greater in 2014 than in 2013. In 2013, the j-value measure of agreement between the two experts ranged from ＂poor＂（κ=–0.051） to ＂good＂（κ=0.968）. The AC1 measure of agreement between the experts was generally high for the indicators and ranged from –0.010 to 0.978. In most cases, agreement was considerably lower when it was assessed by the j-values compared with the AC1 values. In 2014, the j-value measure of agreement on the indicators（for the subjects） general y ranged from poor to good, with the values ranging from –0.007 to 0.994. Moreover, the AC1 measure of agreement between the experts was general y high for al of the indicators and ranged from ＂moderate＂（AC1=0.408） to ＂excel ent＂（AC1=0.996）. Conclusions： In four examinations, there was moderate agreement between the clinicians on the PI indicators of blood stasis. To improve clinician consistency（e.g., in the diagnostic criteria used）, it is necessary to analyse the reasons for inconsistency and to improve clinician training.（Trial registration No. KCT0000916）

Recognition of Association Between Blood Stasis Syndrome and Traumatic Injury among Doctors of Korean Medicine:A Cross-Sectional Observation Study

引用

Chinese Journal of Integrative Medicine 2018年第4期24卷 254-259页

作者： Jeeyoun jung mi mi Ko Ju Ah Lee Myeong Soo Lee Korean Medicine Fundamental Research Division Korea Institute of Oriental Medicine Clinical Research Division Korea Institute of Oriental Medicine

Objective： To investigate the diagnostic indicators and herbal treatments for blood stasis syndrome（BSS） patients with traumatic injuries and to identify the association between BSS and traumatic injury in Korea. Methods： Two-hundred and four patients with traumatic injury were recruited from the Gangnam and Daejeon branches of Jaseng Hospital of Oriental Medicine between June 2014 and December 2014. Two independent doctors of Korean medicine（DKMs） determined the diagnosis of BSS or non-BSS based on the subjects＇ signs and symptoms. The scores assigned to BSS symptoms and DKMs＇ reasons for diagnosing BSS in patients with traumatic injury were investigated. Both medication and herbal prescription records from a 3-month period were collected for all patients diagnosed with BSS by both DKMs. Results： A total of 169 of 204（82.8%） patients received consistent diagnosis related to BSS by two DKMs. Among them, 54.4%（92 cases） were diagnosed with BSS, and 45.6%（77 cases） were not diagnosed with BSS. DKMs most frequently cited symptoms of recent traumatic injury as justifications for BSS diagnoses, and also selected pain-related indicators such as abdominal pain, sharp pain and nocturnal pain as important reasons in diagnosing BSS. In addition, an inconsistency in the pattern identification theory with respect to traumatic injury was observed. Although only 92 cases（54.4%） of patients were diagnosed with BSS, 77.6% of them were prescribed decoctions for BSS. Conclusions： DKMs considered traumatic injury could cause BSS, and utilized decoction for BSS in patients with traumatic injury without confirming a diagnosis of BSS because they assumed the main symptoms or pathologies of traumatic injury to be closely related to BSS.

Slip-enhanced Reverse Electrodialytic Power Generation in Ion-selective Nanochannels

引用

Journal of Thermal Science 2013年第1期22卷 36-41页

作者： Byeongdong Kang Jaisuk yoo Hyun jung Kim Dong-Kwon Kim Department of Mechanical Engineering Ajou University

Power generation by reverse electrodialysis in ion-selective nanochannels is numerically investigated. Especially,in the present study, the influence of hydrodynamic slip at the surface of nanochannels is investigated. The current-potential characteristics of the nanochannels are calculated by solving several governing equations:Nernst-Planck equation for the ionic concentrations, the Poisson equation for the electric potential, and the Navier-Stokes equation for the diffusioosmotic flow. Hydrodynamic slip is applied as the boundary condition at the surface of nanochannels. As the slip length increases, the diffusioosmotic flow velocity and electrical conductance of ions increase because the friction at the surface of nanochannels decreases. It is shown that the power generation is enhanced by 44% with a moderate 100nm slip length by using a nanochannel with 10nm height.

Objective： To investigate the important diagnostic indicators for blood stasis syndrome （BSS） in patients of childbearing age with gynaecological diseases. Methods： A partial least squared-discriminant analysis （PLS-DA） were applied to BSS symptoms data of patients with gynaecological diseases, and the diagnostic indicators used by doctors of Korean medicine （DKMs） among BSS patients with gynaecological diseases were also investigated. Results： A total of 103 patients of childbearing age with gynaecological diseases and 40 healthy controls were enrolled. Among the 103 patients, 63 （61.7%） and 40 （38.8%） were diagnosed with BSS and non-BSS, respectively, and BSS patients exhibited a more severe extent of disease. A score plot of PLS-DA showed clearly different patterns among the 3 groups. Based on the variable importance on projection of PLS-DA model, menstrual pains, dark lumps in the menstrual blood, ileocoecal tenderness and resistance, sharp pains, and sublingual varicosities were selected as the top five most important indicators. Moreover, more than 75% of DKMs chose dark lumps in menstrual blood, menstrual pain, and dark menstrual blood as the diagnostic indicators of BSS in patients with gynaecological diseases, and more than 49% of them also considered sharp pains, dark red tongue, sublingual varicosities, and tendency to bruise easily as diagnostic indicators of BSS. Conclusion： DKMs focused on menstrual symptoms and certain gynaecological symptoms to diagnose BSS patients of childbearing age with female diseases.

Flow Visualization and Performance Measurements of a Flagellar Propeller

引用

Journal of Bionic Engineering 2012年第3期9卷 322-329页

作者： Hyejin Jeon yoon-Cheol Kim Dongwook Yim jung Yui yoo Songwan Jin School of Mechanical and Aerospace Engineering Seoul National University Seoul 151-744 Korea Department of Mechanical Engineering Korea Polytechnic University Siheung-si Gyeonggi-do 429-793 Korea

A new type of propeller that is optimized for low Reynolds numbers is required to propel a small object in a medium where the flow is dominated by viscous rather than inertial forces. A propeller in the shape of a bacterial flagellum seems an appro- priate choice for driving a small object. Accordingly, in this study, we visualized the velocity field induced by a spring-like propeller inspired by the Escherichia coli flagellum, using a macroscopic model and applying stereoscopic particle image velocimetry. We also experimentally evaluated the effect of pitch and rotational speed on the performance of this flagellar propeller. Silicone oil, which has a kinematic viscosity 100,000 times that of water, was used as the working fluid to generate a low Reynolds number for the macroscopic model. Thrust, torque, and velocity were measured as functions of pitch and rota- tional speed, and the efficiency of the propeller was calculated from the measured results. We found that the flagellar propeller reached a max!mum efficiency when the pitch angle was approximately 53°. Compared to pitch, rotational speed had a relatively small effect on the efficiency, and the pitch altered the flow pattern behind the rotating propeller.
