Hollow fiber membrane G-L contactors are widely used to remove $SO_2$ emitted from industrial facilities. In this work, the mathematical modeling and computer simulation for hollow membrane G-L contactors is carried out to analyze $SO_2$ absorption behavior in hollow fiber membranes. The model is solved with the finite element method using a commercial software. Investigated is the dependency of $SO_2$ removal efficiency and mass transfer characteristics on gas velocities, membrane mass transfer coefficients and physical properties of contactors. The membrane mass transfer coefficients are estimated by fitting the experimental data with the simulated $SO_2$ removal efficiencies. In addition, a design methodology of membrane contactors is suggested.

Objectives : The purpose of this study is to compare the efficacy after acupuncture on local acupoints group and distal acupoints group for chronic neck pain. Design : A randomized, crossover clinical trial. Methods : From 15st, September 2010 to October 30th, 2010. 20 patients with chronic neck pain were randomly assigned to either group A or group B. Group A received acupuncture at local acupoints then after 1 week washout period acupuncture at distal acupoints. Group B received the treatment in reverse order. To evaluating efficiency and satisfaction, visual analog scale(VAS), neck disability index(NDI), cranio-cervical flextion test(C-CFT) and five-point likert scale were measured before and after each treatment. Results : Patients in local acupoints group experienced greater improvement than distal acupoints group in VAS. Both local acupoints group and distal acupoints group showed significant improvement in NDI but not in C-CFT and the NDI score change comparison between the two groups had no significance. Local acupoints group showed more effective than distal acupoints group on five-point likert scale. Conclusions : Local acupoints is more effective than distal acupoints in controlling pain in chronic neck pain.

Objectives : Recent well-designed randomized controlled trials(RCTs) and their meta-analysis have been published on the efficacy of acupuncture in different condition. In most of them, real acupuncture is compared with sham acupuncture including invasive and non-invasive sham methods. But it is not clear how active sham methods are. These results tend to lead the conclusion that acupuncture has no more effective than sham acupuncture. In order to investigate that sham acupuncture is appropriate as a control, we reviewed several acupuncture trials using different sham acupuncture as a control. Methods : We searched Cochrane researches of acupuncture, reviewed and analyzed 25 RCTs in 42 Cochrane reviews. And especially we compared the effect of acupuncture according to the type of sham acupuncture. Results : Invasive sham acupunctures are used in 12 RCTs and non-invasive types are used in the rest. The majority of studies(19 RCTs) fail to show effects beyond a sham acupuncture. Streitberger's sham needle is a validated sham acupuncture of non-invasive type that was used in 8 trials and also no significant group differences are shown except one trial. Conclusions : Acupuncture is a complex intervention. Clinical trials of acupuncture need to be reexamined and redesigned to remove several bias. Especially, sham acupuncture as a control might be investigated for physiological effects as well as validation test including patient-blinding and de qi sensation. Other research need to be investigated and developed for acupuncture trials.

We have performed high-level quantum mechanical calculation for multiple proton transfer in HOCl + HCl and $H_2O$ + $ClONO_2$ on water clusters, which can be used as a model of the reactions on ice surface in stratospheric clouds. Multiple proton transfer on ice surface plays crucial role in these reactions. The structures of the clusters with 0-3 water molecules and the transition state structures for the multiple proton transfer have been calculated. The energies and barrier heights of the proton transfer were calculated at various levels of theory including multi-coefficient correlated quantum mechanical methods (MCCM) that have recently been developed. The transition state structures and the predicted reaction mechanism depend very much on the level of theory. In particular, the HF level can not correctly predict the TS structure and barrier heights, so the electron correlation should be considered appropriately.

The purpose of this study is to investigate the effect of SoSikCheongWool-Tang on white rats' hepatocyte damages induced by Radix Aconitine. For the study, Radix Aconitine was administered to white rats, damaging their hepatocytes, and then SoSikCheongWool-Tang was given to the rats. As a result, the following histological changes of the hepatocytes were observed through light and electron microscope: 1. Radix Aconitine damaged the congestion, necrosis and hemolysis in the liver. 2. In the six-hour control group, the cisternae of rough and smooth endoplasmic reticula were dilated or disoriented, and the attached ribosomes of rough endoplasmic reticulum were hardly observed. 3. In the three-day control group, the destruction of the nucleus as well as the damage of all the cell-organelles was observed. 4. In all the experiment groups, the rats, after given SoSikCheongWool-Tang, quickly recovered from the cytotoxicity induced by aconitine extracts. From the above results, this study has come to the conclusion that SoSikCheongWool-Tang is efficacious against the cytotoxicity induced by Radix Aconitine.

1. Objectives: This study was performed to research the relationship between Sasang Constitution and characteristics of tongue diagnosis based on Donguisusebowon's Experience prescriptions(經驗方). 2. Methods: We searched tongue diagnosis factors in Donguisusebowon and classified this. Based on Donguisusebowon's Experience prescriptions(經驗方), we find tongue diagnosis factors in 6 contemporary Oriental medicine prescription books. 3. Results: Most So-eumin has white thin tongue coating and clear redish tongue color. Yellow tongue coatings are found in symptoms for Yinjinho-tang(Yinchenhao-tang), Soseungki-tang(Xiaochengqi-tang), Daeseungki-tang(Dachengqi-tang). Shortened Tongue is found in So-eumin's experience prescription and So-yangin's treat histroy. It didn't shown that So-eumin's Semen Crotonis included 6 prescritions' factors of tongue diagnosis. So-yangin's white tongue coating is found in Hyungbangpaedok-san(Jingfangbaidu-san), Sipjo-tang(Shizao-tang), Sosiho-tang(Xiaocihu-tang), Shinki-hwan(Shenqi-wan). Most of other So-yangin's tongue coatings are Yellowish and tongue color is deep red. Tae-eumin have thin white tongue coating at the Mahuang-tang(Mahuang-tang). Red tongue color and drying tongue are found at Jowiseungki-tang(Tiaoweichengqi-tang)Daesiho-tang(Dacihu-tang)Saengmaek-san(Shengmai-san) 4.

'Hwan So Dan(還少丹)' is Chinese patent medicine which has been used for shortage of vitality and asthenia in Korea. It consists of 14 kinds of powdered crude drugs. In powdered crude drugs, it is hard to identify each component by chemical analysis or morphological examination. However, the method of identification of powdered crude drugs has not been clearly established. For the identification of individual crude drugs in such powdery mixtures, microscopic method may advantageously be used as it requires only a small amount specimens. In this study, it is demonstrated that the microscopic method is very effective for the identification of 14 crude drug ingredients in Hwan So Dan.

The purpose of this study was to quantitatively estimate the washout removal efficiencies of criteria air pollutants such as SO$_2$, TSP, PM10, CO, NO$_2$, and O$_3$corresponding to the amounts and durations of precipitation. The removal patters by washout were studied with air pollutants data and the corresponding precipitation data in Seoul, Korea during the periods of 1990 to 1999. In addition, washout patterns were classified into four seasons and four time Bones, i.e., night, morning, afternoon, and evening. In this study, natures of air pollutants by sequential precipitation were also intensively studied by examining the linear relationships between removal efficiencies and the amounts and durations of precipitation for each pollutant. The results of this study showed that SO$_2$, TSP, and O$_3$were rapidly removed by initial precipitation; however, NO$_2$was slowly removed 2-hour after precipitation. Both CO and PM10 were weakly removed by washout and their removal patters showed to be irregular.
