Amis:ST25(Chonchu) and ST37(Sanggoho) are usually used acupoints to management several disease which induced to abnormal intestinal motility as diarrhea, constipation. Colonic transit time by radio opaque marker is able to study easily and useful method for evaluation of colonic motility. The aim of this study was to assess the effect on colonic transit time by manual acupuncture or electroacupuncture stimulation of ST25, ST37 in normal adult. Method: Colonic transit time, including Rt colon, Lt colon, rectosigmoid colon was measured by radio opaque marker in 11 normal adults. Colon transit time was measured before stimulation and after stimulation on ST25, ST37 by manual acupuncture and electroacupuncture. Each person was treated manual acupuncture or electroacupuncture stimulation for 3 days before colonic transit time measurement with 1 week interval. Result: Colon transit time before stimulation was measured $10.60{\pm}12.11$, $3.92{\pm}7.72$, $3.27{\pm}6.37$, $3.41{\pm}5.57$ hours total colon, Rt colon, Lt colon, rectosigmoid colon, respectively. Colon transit time after manual acupuncture is measured $10.48{\pm}12.35$, $3.72{\pm}7.52$, $3.37{\pm}6.76$, $3.39{\pm}5.84$ hours total colon, Rt colon, Lt colon, rectosigmoid colon, respectively. Colon transit time after electroacupuncture stimulation is measured $10.30{\pm}13.21$, $3.92{\pm}8.02$, $3.07{\pm} $, $3.31{\pm}5.49$ hours total colon, Rt colon, Lt colon, rectosigmoid colon, respectively. Significant change was observed Lt colon transit time after electroacupuncture as compared before acupuncture(P<0.05). Conclusion: Theses results suggest that manual acupuncture and electroacupuncture of ST25, ST37 in normal adults does not change colonic transit time.
Background : Asthma is the most common respiratory crisis encountered in clinical practice, occurring in up to 4% of all pregnancies. Pregnancy often appears to alter the course of asthma. But the mechanisms responsible for variable changes in the asthma course during pregnancy remain unknown. Poor control and exacerbations of asthma during pregnancy may result in serious maternal and fetal complications. To investigate the course of asthma during pregnancy in korean women, we did a retrograde study of 27 pregnant women who had been admitted to Korea University Hospital for asthma worsened. Method: Twenty seven pregnant women who had been visited to Korea University Hospital for asthma worsened were enrolled in our retrospective study. We reviewed medical recordings and interviewed patients with asthma. Results: Twenty seven pregnant women with asthma were evaluated, and 25 patients were enrolled to our study. Two patients experienced abortions at 6 weeks and 25 weeks gestation, respectively. The period of asthma worsened was commonly during weeks 20 to 28 of gestation. And all patients wosened were improved during the last 4 weeks of pregnancy. Twenty(80%) of 25 women whose asthma worsened during pregnancy reverted toward their prepregnancy status after delivery(p<0.002). The causes of asthma worsened during pregnancy are reduction or even complete cessaton of medication due to fears about its safety(40%), worsening after upper respiratory infection (28%), and unknown(32%). There were no adverse perinatal outcomes in 25 pregnant asthma subjects. Conclusions: A major problem of therapy for asthma during pregnancy is reduction or even complete cessation of medication due to fears of fetal effects. Therefore, maternal education and optimal clinical and pharmacologic management is necessary to mitigate maternal and fetal complications.

Purpose : Rotavirus is one of the most important etiologic agents of nosocomial infections among the neonates. This study was designed to investigate nosocomial rotavirus infection in neonates who were admitted to a postpartum-care center after birth. Methods : From March 2005 to September 2006, 957 healthy neonates were examined for rotavirus antigen in stool by immunochromatographic method and 216 neonates were rotavirus antigen positive within 24 hours after admitted to a postpartum-care center. We reviewed the nursing charts retrospectively such as characteristics, monthly distribution, birth hospitals, delivery methods, feeding types and clinical manifestations. Results : Among 957 neonates, 216 neonates (22.6%) were rotavirus antigen positive and there were no differences in sex, birth weight, gestational age. Monthly positive rate of rotavirus antigen showed diversity from 10% to 36%. According to birth hospitals, positive rate showed diversity from 3.5% to 53.6%. Out of 957 neonates, 655 cases (68.4%) were born of vaginal delivery and mean hospitalized duration was 2.4 days, 302 cases (31.6%) were born of cesarean section and mean hospitalized duration was 5.7 days. 17.6% of vaginal delivery and 33.4% of cesarean section were rotavirus antigen positive. The positive rate was higher in neonates by cesarean section than vaginal delivery (P<0.001). According to feeding types, positive rate of rotavirus antigen was lower in breast-fed group than formula-fed group (P<0.001). Proportion of symptomatic case among rotavirus antigen positive was 34.7%. Most common clinical manifestation was diarrhea (61.3%), following poor feeding (45.3%), fever (40.0%), vomiting (25.3%), delayed weight gain (12.0%), and decreased urine amount (5.3%). Conclusion : Some neonates were already infected before admission to a postpartum-care center. Without meticulous management, nosocomial rotavirus infection would transmit rapidly in a postpartum-care center spreading to the community. Recommendation of breast-feeding, routine rotavirus screeing test with or without symptom, and isolation of all rotavirus antigen positive neonates in a postpartum-care center seem to be necessary. Also attentive hygiene education and further investigations of rotavirus infection in a postpartum-care center would be needed.

Purpose : To reduce the Irradiation dose to the lungs and heart in the case of chest wail irradiation using an oppositional electron beam, we used an Individualized custom bolus, which was precisely designed to compensate for the differences In chest wall thickness. The benefits were evaluated by comparing the normal tissue complication probablilties (NTCPS) and dose statistics both with and without boluses. Materials and Methods : Boluses were made, and their effects evaluated in ten patients treated using the reverse hockey-stick technique. The electron beam energy was determined so as to administer 80% of the irradiation prescription dose to the deepest lung-chest wall border, which was usually located at the internal mammary lymph node chain. An individualized custom bolus was prepared to compensate for a chest wall thinner than the prescription depth by meticulously measuring the chest wall thickness at 1 emf intervals on the planning CT Images. A second planning CT was obtained overlying the individuailzed custom bolus for each patient's chest wall. 3-D treatment planning was peformed using ADAC-Pinnacle$^{3}$ for all patients with and without bolus. NTCPS based on 'the Lyman-Kutcher' model were analyzed and the mean, maximum, minimum doses, V$_{50}$ and V$_{95}$ for 4he heari and lungs were computed. Results .The average NTCPS in the ipsliateral lung showed a statistically significant reduction (p<0.01), from 80.2${\pm}$3.43% to 47.7${\pm}$4.61%, with the use of the individualized custom boluses. The mean lung irradiation dose to the ipsilateral iung was also significantly reduced by about 430 cGy, Trom 2757 cGy to 2,327 cGy (p<0.01). The V$_{50}$ and V$_{95}$ in the ipsilateral lung markedly decreased from the averages of 54.5 and 17.4% to 45.3 and 11.0%, respectively. The V$_{50}$ and V$_{95}$ In the heart also decreased from the averages of 16.8 and 6.1% to 9.8% and 2.2%, respectively. The NTCP In the contralateral lung and the heart were 0%, even for the cases with no bolus because of the small effective mean radiation volume values of 4.4 and 7.1%, respectively Conclusion : The use of an Individualized custom bolus in the radiotherapy of postrnastectorny chest wall reduced the NTCP of the ipsilateral lung by about 24.5 to 40.5%, which can improve the complication free cure probability of breast cancer patients.
The shear load distribution and deformation of offshore friction piles are investigated using experimental tests and a numerical analysis. Special attention is given to the soil-pile interaction of axially loaded pile. A framework for determining the f-w curve is proposed based on both theoretical analysis and experimental load test data base. A numerical analysis that takes into account the proposed f-w curves was performed for major parameters on pile-soil interaction such as the pile diameter, the pile length, and the soil condition. Based on the analysis, it is shown that the proposed f-w method is capable of predicting the behavior of a friction pile in deep soft clay. Through comparisons with case histories and finite element results, it is found that the proposed f-w curves are more appropriate and realistic m representing the pile-soil interaction of axially loaded piles in deep soft clay than that of existing f-w method.

Recently, buildings tend to be large size, complex shape and functional. As the size of buildings is becoming massive, the need for structural health monitoring (SHM) technique is increasing. Various SHM techniques have been studied for buildings which have different dynamic characteristics and influenced by various external loads. "Abnormal behavior point" is a moment when the structure starts vibrating abnormally and this can be detected by comparing between before and after abnormal behavior point. In other words, anomalous behavior is a sign of damage on structures and estimating the abnormal behavior point can be directly related to the safety of structure. Abnormal behavior causes damage on structures and this leads to enormous economic damage as well as damage for humans. This study proposes an estimating technique to find abnormal behavior point using Hilber-Huang Transform which is a time-frequency signal analysis technique and the proposed algorithm has been examined through laboratory tests with a bridge model using a shaking table.
To determine the proper carbon and nitrogen sources and their proper levels for mass micro propagation of Scrophularia buergeriana Miquel, tonic and curing cough experiment were applied and a method for mass cultivation by using bioreactors (2.5 L) was expinined. Proper ratio of $NH_4NO_3\;:\;$KNO_3$ was 413 mg/L : 1900 mg/L for multiple shoot production. Sucrose was more effective than glucose or fractose as carbon source and 3% concentration was good for shoot formation. Total nitrogen was not detected after six weeks both in 500 ml flask and bioreactor culture. Sucrose was decreased sharply after two weeks and there was no sucrose left after three weeks both in 500 ml flask and bioreactor culture. The stirrer in bioreactor caused shear stress to shoots severely. The sphere type bioreactor was better than the cylinder type and removal of inner loop in sphere type was more effective to avoid shear stress.
The purpose of this study is to establish experimental canine skin barrier disruption model in dog. The study was designed to investigate the predictive properties of acetone damage using as effect parameters transepidermal water loss (TEWL) and stratum corneum (SC) hydration. To compare the structures of SC intercellular lipids in normal and acetone damaged skin, TEM observations were performed. Six clinically normal, male Beagles without dermatological problems were chosen for this study. Acetone damage was performed at 48hrs after clipping. Efficacy measurements for TEWL and skin hydration were performed before ($t_1$) and after ($t_2$) damage in a temperature- and humidity-controlled room ($2{0\sim}22^{\circ}C$, 50-60%). TEWL and SC hydration values were decreased in the acetone damaged model compared with non damaged skin. In TEM observation of acetone damaged sample, the intercellular lipid lamellae exhibit abnormal and incomplete structure compared with those of normal skin. It seems that acetone damage would be one of canine skin epidermal barrier disruption model for the study of canine atopic dermatitis (AD) as well as dry skin in veterinary dermatology research.
There has been an increased awareness of the need to confirm the chloroform exposure associated with using chlorinated household water. Ten of a 30-minute tub bath were normally taken by two volunteers in a bathroom of an apartment. Chloroform concentrations were measured in bathing water and bathroom air, and exhaled breath of the subjects prior to and after bathing. Bathing using chlorinated tap water resulted in a chloroform exposure and caused a body burden. Based on the difference of chloroform concentrations between breath samples collected prior to and after bathing, the chloroform body burden from a 30-minute bath was estimated to be about 8 to 26 folds higher than that prior to the bath. The mean water and bathroom air chloroform concentrations measured to evaluate the body burden were $9.4\mu\textrm{g}/l$ and TEX>$14.9\mu\textrm{g}/m^3$, respectively. The chloroform level of the bathroom air was 각 to 130 times higher than that of the living-room air. The relationship between the bathroom air and the corresponding breath chloroform concentrations were significant with p=0.03 and $R^2=0.47$.
