To find out the actual status of treatment of physically handicapped who were stayed of home, 320 physically handicapped persons were selected among total 6,264 physically handicapped registered in Taejon city, surveyed from January 1st to March 30, 1997. Following are the results ana lysed of collected data from 201 samped persons. 1. For the cause of physically handicapped, 36.3% was congenital, 26.9% was cerebralvascular acciednt(CVA). and 14.9% was infectious diseases and others in that orders. The must frequest cause of below 20 years age group was congenital cause, but that of $20{\sim}30$ years age group and $40{\sim}50$ years age group were accident and CVA repectively. 30.0% of respondents caused by infection and others earned household living expenses. Household living expenses were higher among the respondents caused by congenital cause but those were lowest in the accidental couse group. Handicap durations were longer in the accidental cause group and infections and others group than the congenital cause group and CVA group. 2. 54.7% of studied handicapped were under treatment. But 36.3% of them were stopped treatment, and 8.9 % of them answered not treated. Most handicapped, coused by congenital and CAV, were under treatment, but most of them caused by accidental and others were stopped treatment. 3. For the medical facilities, 54.5% of them utilized welfare facility, but 25.5% utilized general hospital and 20.0% of them utilized oriental medical hospital and health centers. Congenital cause group frequently selected welfare facility for the treatment facility. But accidental cause group frequently seleced general hospitals and CVA gruop frequently selected oriental medical hospital and others. The medical cost of welfare facility, oriental medical hospitals and others were lower than that of general hospitals. 4. The proportions of under treatment were higher among yonger age higher monthly living expenses group shorter handicapped duration groups, congenital cause group and handicap grade II group. But that of stop treatment were higher among congenital cause group, infectious and others cause group, and handicap grade I & then III group. 5. For the feelings satisfacion about medical treatment, only 35.3% of under treated group responed satisfation. 55.5% of them responded so-so, but 9.1 % responed dissatisfaction. The proportion of satisfaction was higher among shorter handicap duration group.

Apios americana Medik (hereinafter Apios) has been reported to treat diseases, including cancer, hypertension, obesity, and diabetes. The therapeutic effect of Apios is likely to be associated with its anti-inflammatory activity. This study was conducted to evaluate the protective effects of Apios in animal models of acute lung injury induced by lipopolysaccharide (LPS) or pandemic H1N1 2009 influenza A virus (H1N1). Mice were exposed to LPS or H1N1 for 2-4 days to induce acute lung injury. The treatment groups were administered Apios extracts via oral injection for 8 weeks before LPS treatment or H1N1 infection. To investigate the effects of Apios, we assessed the mice for in vivo effects of Apios on immune cell infiltration and the level of pro-inflammatory cytokines in the bronchoalveolar lavage (BAL) fluid, and histopathological changes in the lung. After induction of acute lung injury, the numbers of neutrophils and total cells were lower in the Apios-treated groups than in the non-Apios-treated LPS and H1N1 groups. The Apios groups tended to have lower levels of tumor necrosis factor-a and interleukin-6 in BAL fluid. In addition, the histopathological changes in the lungs were markedly reduced in the Apios-treated groups. These data suggest that Apios treatment reduces LPS- and H1N1-induced lung inflammation. These protective effects of Apios suggest that it may have therapeutic potential in acute lung injury.

Because of its elevated cellulolytic activity, the filamentous fungus Trichoderma harzianum has a considerable potential in biomass hydrolysis applications. Trichoderma harzianum cellobiohydrolase I (ThCBHI), an exoglucanase, is an important enzyme in the process of cellulose degradation. Here, we report an easy single-step ion-exchange chromatographic method for purification of ThCBHI and its initial biophysical and biochemical characterization. The ThCBHI produced by induction with microcrystalline cellulose under submerged fermentation was purified on DEAE-Sephadex A-50 media and its identity was confirmed by mass spectrometry. The ThCBHI biochemical characterization showed that the protein has a molecular mass of 66 kDa and pI of 5.23. As confirmed by smallangle X-ray scattering (SAXS), both full-length ThCBHI and its catalytic core domain (CCD) obtained by digestion with papain are monomeric in solution. Secondary structure analysis of ThCBHI by circular dichroism revealed ${\alpha}$- helices and ${\beta}$-strands contents in the 28% and 38% range, respectively. The intrinsic fluorescence emission maximum of 337 nm was accounted for as different degrees of exposure of ThCBHI tryptophan residues to water. Moreover, ThCBHI displayed maximum activity at pH 5.0 and temperature of $50^{\circ}C$ with specific activities against Avicel and p-nitrophenyl-${\beta}$-D-cellobioside of 1.25 U/mg and 1.53 U/mg, respectively.

Particulate matter (PM) data collected from the Urban Air Monitoring Network in Busan during the period from 2006 through 2010 were statistically examined and analyzed to estimate the probability of exceeding $PM_{2.5}$ 24 hour and annual standard to be implemented from January $1^{st}$, 2015. For Jangrimdong, Yeonsandong, Kijangeup, and Jwadong where simultaneous measurement of $PM_{10}$ and $PM_{2.5}$ was conducted, the probability of exceeding $PM_{2.5}$ standards was estimated using $PM_{2.5}$ data measured on site. For other areas where there were no measured $PM_{2.5}$ data available, the probability of exceeding $PM_{2.5}$ standards was statistically estimated using $PM_{10}$ measured on site and $PM_{2.5}/PM_{10}$ ratios obtained from the four stations where both $PM_{2.5}$ and $PM_{10}$ were monitored simultaneously. At Jangrimdong, Yeonsandong, Kijangeup, and Jwadong, mean value of annual 99 percentile of 24 hr average $PM_{2.5}$ for 5 years from 2006 through 2010 was 99.3, 74.5. 57.0, and $62.5{\mu}g/m^3$, respectively, and the probability of exceeding $PM_{2.5}$ 24 hr standard was estimated at 100%. For areas where there were no measured $PM_{2.5}$ data available, the estimated probability of exceeding $PM_{2.5}$ 24 hr standard was more than 0.82. Mean value of annual average $PM_{2.5}$ from 2008 through 2010 was 31.7 and $27.6{\mu}g/m^3$ for Jangrimdong and Yeonsandong, respectively, which exceeded $PM_{2.5}$ annual standard of $25{\mu}g/m^3$. Mean value of annual average $PM_{2.5}$ during the same period for Kijangeup and Jwadong was 19.2 and $20.7{\mu}g/m^3$, respectively, which satisfied $PM_{2.5}$ annual standard. For other areas where there were no measured $PM_{2.5}$ data available, the probability of exceeding $PM_{2.5}$ annual standard was more than 0.95 except Taejongdae and Kwangahndong. With $PM_{10}$ and $PM_{2.5}$ data measured at 17 Urban Air Monitoring Stations in Busan, the probability of exceeding $PM_{2.5}$ standards was estimated to be very high for almost all areas. This result indicates that proper measures to mitigate $PM_{2.5}$ in Busan should be investigated and established as soon as possible.

Objectives : The purpose of this study is to compare interrelations between primary headache (including migraine) and Iris Constitution through iris constitution examination. Methods : The subjects were 50 patients who admitted to Chonju Oriental Medicine Hospital attached to Wonkwang Univ. from February.1st.2004 to March.31th.2005. The subjects were constituted of primary headache(including migraine) patients who were examined by Iris Constitution analysis. Results & Conclusion : Among 50 cases of primary headache(including migraine) the distribution of Iris Constitution were as follows. 1. There were 14 cases of neurogenic type, 9 cases of abdominal connective tissue weakness type, 8 cases of cardio-renal connective tissue weakness type, 6 cases of neurogenic + abdominal connective tissue weakness type, 5 cases of neurogenic type+ cardio-renal connective tissue weakness type, 5 cases of abdominal connective tissue weakness type + cardio-renal connective tissue weakness type, 2 cases of hydrogenic type, 1 case of abdominal connective tissue weakness type + mesenchymal pathological connective tissue weakness constitution. 2. There were 25 cases of which included neurogenic constitution, 21 cases of which included abdominal connective tissue weakness constitution, 18 cases of which included cardio-renal connective tissue. Migraine have a meaningful interrelation with Iris constitution, especially with neurogenic type, abdominal connective tissue weakness type and cardio-renal connective tissue weakness type. 3. Interrelation between Region of migraine and Iris constitution is non-specific with the exception of interrelation between pain in all over head with neurogenic type. These results suggest that the further study in connection with these results should be followed. 4. The interrelation between the period of migraine and Iris constitution is not remarkable.

Objectives : The electroacupuncture(EA) was often used in Oriental medicine clinic and basic researches. However, there have been neither any national standard of acupuncture needles in Korea nor many studies about the property of acupuncture needles for applying electrical stimulations. Therefore we investigated the electrical corrosion property of acupuncture needles used for EA stimulation in clinic. Methods : We observed the occurrence of electrical corrosion like changes in the surface of acupuncture needles after EA stimulation with various parameters(electrical stimulation intensity, treatment duration, diameter of needle) under a light microscope. We performed EA stimulation on Baekhoe($GV_{20}$) or Joksamli($ST_{36}$) of rats with intensity of 0.025, 0.05, 0.075, 0.1, 0.25 or 0.5mA at a 10Hz frequency. Results : The electrical corrosion-like changes were found on the surface of needles when the EA stimulation was given over 0.05mA of intensity. When electrical stimulation was treated for 10min, the electrical corrosion-like changes were low, but the electrical corrosion-like changes gradually increased by the treatment duration(20, 30min). We also found that acupuncture needles of 0.2mm diameter were produced more extensive electrical corrosion-like changes than acupuncture needles of 0.3 or 0.4mm diameter by electrical stimulation. Conclusions: These results suggested that EA stimulation could produce electrical corrosion-like changes of acupuncture needles through intensity of current, duration of electric stimulation and/or diameter of needle.

To estimate the characteristics of Korean Ni-Ti alloy orthodontic wire, this study investigated compositions, tensile properties, bending properties, heat treatment effects, and ion releasing degrees, and compared these characteristics to those of the imported Ni-Ti alloy wire. The results obtained are as follows ; 1. Ti and -Ni elements in ORTHOLLOY were in a range showing superelasticity, and there was a little difference in the Ni and Ti contents of ORTHOLLOY as compared with those of SENTALLOY. 2. The results of the tensile test concerning ORTHOLLOY exhibited a superelastic effect, indicating an area of a definite amount of stress in spite of the changes in the range from $2\%\;to\;8\%$ in the strain rate. 3. ORTHOLLOY presented higher load values than SENTALLOY in the same deflection values when the wire was tested in three-point bending. A load range displaying a superelastic effect was 80-l00g, 140-l80g, and 130-200g respectively, in wire diameters of 0.014', 0.016', and 0.018' 4. By heat treatments at $400^{\circ}C$ and at $500^{\circ}C$, a load range showing the effect of superelasticitly was lessened by the duration of the heat treatment time. The superelastic effect was destroyed as a result of the 10 minutes heat treatment at $600^{\circ}C$. 5. The quantity of the Ni ion released from ORTHOLLOY, tended to be greater than the amount of released Ni ion in SENTALLOY. The Co ion released was very little(<0.01ppm) in SENTALLOY and ORTHOLLOY irrespective of the lapse of time. Released Ni ions on the 1st day were at the maximum, and the releasing rate showed plateaus after three days. 6. The surface morphology of SENTALLOY was relatively regular irrespective of the lapse of rime, and the corrosion tendency was not observed. However, the surface morphology of ORTHOLLOY was rather irregular and shelved fitting corrosion after immersion.

In the orthopedic therapy, the biomechanical analysis of the appliance is necessary to get a desirable orthopedic effect. The purpose of this study was to investigate the desirable direction and application position of the protraction force. The protraction force of 500g was applied to the first premolar or to the first molar. The direction of force application was paralell or $20^{\circ}$ downward to the occlusal plane respectively. The stress distribution and the displacement within the maxilla was analyzed by a 3-dimensional finite element method. The findings obtained were as follows 1. Protraction forces caused a counterclockwise rotation of the maxilla. 2. The degree of maxillary rotation was less when the force was applied $20^{\circ}$ downward direction to the occlusal plane than when applied to the parallel direction. 3. The degree of rotation of maxilla was greater when the parallel force was applied to the 1st premolar than when applied to the first molar, whereas it was greater when force is applied $20^{\circ}$ downward than at the first premolar. In conclusion, the $20^{\circ}$ downward protraction from the first premolar induced the least counterclockwise rotation of the maxilla and was thought as the desirable direction and application position of the protraction force.

Nausea and vomiting are among the most serious side effects of chemotherapy, in some cases leading to treatment interruption or chemotherapy dose reduction. Ginger has long been known as an antiemetic drug, used for conditions such as motion sickness, nausea-vomiting in pregnancy, and post-operation side effects. One hundred and fifty female patients with breast cancer entered this prospective study and were randomized to receive ginger (500 mg ginger powder, twice a day for 3 days) or placebo. One hundred and nineteen patients completed the study: 57 of them received ginger and 62 received ginger for the first 3 chemotherapy cycles. Mean age in all patients was 48.6 (25-79) years. After 1st chemotherapy, mean nausea in the ginger and control arms were 1.36 (${\pm}1.31$) and 1.46 (${\pm}1.28$) with no statistically significant difference. After the $2^{nd}$ chemotherapy session, nausea score was slightly more in the ginger group (1.36 versus 1.32). After $3^{rd}$ chemotherapy, mean nausea severity in control group was less than ginger group [1.37 (${\pm}1.14$), versus 1.42 (${\pm}1.30$)]. Considering all patients, nausea was slightly more severe in ginger arm. In ginger arm mean nausea score was 1.42 (${\pm}0.96$) and in control arm it was 1.40 (${\pm}0.92$). Mean vomiting scores after chemotherapy in ginger arm were 0.719 (${\pm}1.03$), 0.68 (${\pm}1.00$) and 0.77 (${\pm}1.18$). In control arm, mean vomiting was 0.983 (${\pm}1.23$), 1.03 (${\pm}1.22$) and 1.15 (${\pm}1.27$). In all sessions, ginger decreased vomiting severity from 1.4 (${\pm}1.04$) to 0.71 (${\pm}0.86$). None of the differences were significant. In those patients who received the AC regimen, vomiting was less severe ($0.64{\pm}0.87$) comparing to those who received placebo ($1.13{\pm}1.12$), which was statistically significant (p-Value <0.05). Further and larger studies are needed to draw conclusions.
