Objectives : The purpose of this study was to investigate the real status of the utilization of Korean medicine (KM) treatment among children with cerebral palsy (CP). Methods : In a prospective observational multicenter study for children with CP aged from 6 months to 78 months, we analyzed 69 questionnaires of children currently receiving or have received KM treatment such as acupuncture and Korean herbal medicine for CP. Results : Of all the 170 participants, 32 children was currently getting KM treatment and they were getting acupuncture therapy 2.5 times per week on average. The mean expenditure per month for acupuncture and herbal medicine was respectively 32,000won and 501,000won. 37 children have discontinued KM treatment. The most frequent reason for quitting acupuncture therapy was 'inconvenience' (40.7%), followed by 'suffering of children' (33.3%). The average duration of taking Korean herbal medicine was 3.78 months and the highest reason of stopping medicine was 'rejection of children' (32.3%), followed by the 'cost burden' (22.6%). 75% of currently KM using group answered they have experienced positive effect of KM and the rate was 48.6% among the group who have ceased KM. There was a significant difference between the two groups(p=0.025). Conclusions : Further study will be required to increase the therapeutic effect and utilization of KM among the children with CP. More efforts should be made to develop less invasive acupuncture method and various shape of KM herbal medicine and to expand the insurance coverage of KM for children with CP.

ELISA method was applied for the screening of zearalenone producing strains. The developed ELISA was as follow: $125\;{\mu}l$ of diluted solution (1 : 500) of antibody was added to each microtiter well and incubated overnight at $40^{\circ}C$. For direct competitive ELISA, samples and zearalenone-peroxidase conjugate were mixed in a 1 : 1 ratio, and a $100\;{\mu}l$ of aliquot was then added to antisera-coated wells. Plates were incubated for 30 minutes at $37^{\circ}C$, and wells washed 6 times, and $100\;{\mu}l$ of ABTS substrates was added. Plates were incubated for antother 15 minutes at $37^{\circ}C$, and $100\;{\mu}l$ of stopping reagent was added to the wells and absorbance was recorded at 410nm on ELISA Reader. Among 19 strains showed zearalenone-producing ability by ELISA, 3 strains (R-5, C-46, S-134) produced more than 50 ng/ml of zearalenone.

PURPOSES : This study aimed to evaluate the appropriateness of safety with the standard for threshold zone luminance as specified in the Recommendation for Lighting of Traffic Tunnel, which has been widely adopted worldwide. METHODS : A driving test of the subject in a full-scale road tunnel was conducted. The adaptation luminance and threshold zone luminance, which should be known for the driver to perceive an object within stopping sight distance, were obtained. These values were compared with the adaptation luminance and threshold zone luminance obtained by the existing reduced model test and tunnel lighting standard that has served as a guideline for the current threshold zone luminance standard. RESULTS : According to this study, threshold zone luminance should be increased to at least 1.8 times the value proposed in the existing studies and to twice the domestic tunnel lighting standard (KS C 3703: 2014). CONCLUSIONS : The threshold zone luminance proposed in this study differs largely from that obtained from indoor tests and from the current tunnel lighting standard used worldwide; this difference may be attributed to the fact that the indoor tests did not incorporate driving workload, non-uniformity of luminance distribution in terms of sight, and factors that reduce the visibility of the driver, such as the light reflected into the driver's eyes. Hence, it is necessary to further review the factors that reduce the visibility of drivers approaching tunnels in order to determine the rational tunnel threshold zone luminance.

This study was to simulate it that the sending receiving vehicles run on the general national roads with the one-way two-lanes at 80[km/h] speed. This study was to select 280[m] radius of curvature based on the statistical data with high rate of traffic accidents, 140[m] length of direct roads considering the stopping stadia, 90[m] length of curve, and 8 points of curved roads at 11.25[m] intervals. As a result above, when the distance between the sending and receiving vehicles became more than 111[m], the propagation path of reflected wave by the adjacent vehicles became longer than the propagation path of reflected wave by the left/right reflectors because the number of repeated reflection increased. In this study, the repeated reflection for the propagation's reach to the receiving vehicles was about $1{\sim}2$[times] as it supposed it less than 111[m]. Accordingly, it found out that the propagation path of reflected wave received through the left/right reflectors was about $1{\sim}1.5[m]$ larger than the reflected wave produced by the adjacent vehicles regardless of lanes on which the sending and receiving vehicles were located.

Purpose: To compare the efficacy and toxicity of gemcitabine versus docetaxel in a second-line setting of nonsmall cell lung cancer (NSCLC) patients previously treated with platin-based combination chemotherapy. Materials and Methods: We retrospectively evaluated the medical records of 57 patients treated with single agent gemcitabine or docetaxel in second-line setting of advanced NSCLC who received one prior platinum-based therapy. Results: The mean age was $56.7{\pm}8.39$ years with 55 (96.5%) males and two (3.5%) females. Forty of them received docetaxel and 17 gemcitabine. The mean number of chemotherapy cycles was $6.8{\pm}4.0$ in the gemcitabine group, while it was $4.6{\pm}3.0$ in the docetaxel group. Overall response rates were 8% and 12% (P=0.02) for gemcitabine and docetaxel, respectively. The median survival time was 22 versus 21 months for gemcitabine and docetaxel, respectively. The median times to progression were 8 and 5 months. There was no difference between the two groups in terms of incidence of adverse affects (40% vs 47.1%). All of the hematological side effects were grade 1/2. No major toxicity was encountered necessitating stopping the drug for either group. Conclusions: Treatment with gemcitabine demonstrated clinically equivalent efficacy with a significantly improved safety profile compared with those receiving docetaxel in the second-line setting for advanced NSCLC in this study. Based on these results, treatment with gemcitabine should be considered a standard treatment option for second-line NSCLC.

In this inquiry, I would suggest jet ventilation system for effective elimination of welding flaw at machinery material welding shop on plant and evaluate the airstream on inner space and property of welding flaw's density through the examination. We can know outer atmosphere inflows at the speed of about 0.05m/s from western entrance in case of stopping the jet ventilation system, but airstream is accumulated on entire space. At height of worker's breathing surface(Ground Level = 1.5 m, below of GL) and welding work center, density of welding flaw on upper part(GL = 12m) is appeared 4 times higher than outer atmosphere at surplus range besides nearby of western entrance. At operation of jet ventilation system, since the smooth air current transfer at inner space and exhaust effect the wind speed is maintained at 0.932 m/s at the point of height of worker's breathing surface on inner space and it's concluded about the working conditions have been better than before operation of jet ventilation system because of that results show that inner space density of welding flaw at height of worker's breathing surface is 40.5%, and in the work shop, it is 20.3% at upper part.

Anatomy: The rotator cuff comprises four muscles-the subscapularis, the supraspinatus, the infraspinatus and the teres minor-and their musculotendinous attachments. The subscapularis muscle is innervated by the subscapular nerve and originates on the scapula. It inserts on the lesser tuberosity of the humerus. The supraspinatus and infraspinatus are both innervated by the suprascapular nerve, originate in the scapula and insert on the greater tuberosity. The teres minor is innervated by the axillary nerve, originates on the scapula and inserts on the greater tuberosity. The subacromial space lies underneath the acromion, the coracoid process, the acromioclavicular joint and the coracoacromial ligament. A bursa in the subacromial space provides lubrication for the rotator cuff. Etiology: The space between the undersurface of the acromion and the superior aspect of the humeral head is called the impingement interval. This space is normally narrow and is maximally narrow when the arm is abducted. Any condition that further narrows this space can cause impingement. Impingement can result from extrinsic compression or from loss of competency of the rotator cuff. Syndrome: Neer divided impingement syndrome into three stages. Stage I involves edema and/or hemorrhage. This stage generally occurs in patients less than 25 years of age and is frequently associated with an overuse injury. Generally, at this stage the syndrome is reversible. Stage II is more advanced and tends to occur in patients 25 to 40 years of age. The pathologic changes that are now evident show fibrosis as well as irreversible tendon changes. Stage III generally occurs in patients over 50 years of age and frequently involves a tendon rupture or tear. Stage III is largely a process of attrition and the culmination of fibrosis and tendinosis that have been present for many years. Treatment: In patients with stage I impingement, conservative treatment is often sufficient. Conservative treatment involves resting and stopping the offending activity. It may also involve prolonged physical therapy. Sport and job modifications may be beneficial. Nonsteroidal anti - inflammatory drugs(NSAIDS) and ice treatments can relieve pain. Ice packs applied for 20 minutes three times a day may help. A sling is never used, because adhesive capsulitis can result from immobilization.

DSC was used to investigate the thermal mechanism of acorn and corn starch with or without saccharides on gelation and retrogradation. When the samples were starch-saccharide-water system (s-s-w), from measuring of gelation enthalpy and temperatures of initial gelation, peak and conclusion(T$\_$0/, T$\_$p/, T$\_$c/), those of s-s-w system were higher than those of stank-water system (s-w). The retrogradation enthalpy of acorn starch and corn starch was straightly increasing by DSC measurement as storage times. This increase meant slowly becoming recrygtallization of amylopectin. In retrogyadation process, the starch-saccharide-water system's enthalpy was also increased. After 7 days went, the value of the enthalpy was steady. Saccharides were retarding retrogrodation because of stopping the recrystallization of amylopectin. Especially in using fructose and maltose, the retrogradation effect of maltose was well. These elements took effect the number of juntion zone, one of equatorial OH and dynamic hydration number. As these three elements were increasing, a starch-Rel-system was stabilizing.

The absolute absorbed dose can be determined according to the measurement conditions ; measurement material, detector, energy and calibration protocols. The purpose of this study is to compare the absolute absorbed dose due to the differences of measurement condition and calibration protocols for photon beams. Dosimetric measurements were performed with a farmer type PTW and NEL ionization chambers in water, solid water, and polystyrene phantoms using 6MV photon beams from Siemens linear accelerator. Measurements were made along the central axis of $10{\times}10cm$ field size for constant target to surface distance of 100cm for water, solid water and polystyrene phantom. Theoretical absorbed dose intercomparisons between TG21 and IAEA protocol were performed for various measurement combinations on phantom, ion chamber, and electrometer. There were no significant differences of absorbed dose value between TG2l and IAEA protocol. The differences between two protocols are within $1\%\;while\;the\;average\;value\;of\;IAEA\;protocol\;was\;0.5\%$ smaller than TG2l protocol. For the purpose of comparison, all the relative absorbed dose were nomalized to NEL ion chamber with Keithley electrometer and water phantom, The average differences are within $1\%,\;but\;individual\;discrepancies\;are\;in\;the\;range\;of\;-2.5\%\;to\;1.2\%$ depending upon the choice of measurement combination. The largest discrepancy of $-25\%$ was observed when NEL ion chamber with Keithley electrometer is used in solid water phantom. The main cause for this discrepancy is due to the use of same parameters of stopping power, absorption coefficient, etc. as used in water phantom. It should be mentioned that the solid water phantom is not recommended for absolute dose calibration as the alternative of water, since absorbed dose show some dependency on phantom material other than water. In conclusion, the trend of variation was not much dependent on calibration protocol. However, It shows that absorbed dose could be affected by phantom material other than water.
