In Positron Emission Tomography Computed Tomography, Standardized Uptake Value(SUV)is most generally used to discern tumors. However, SUV may be influenced other factors. In this study, experiment was conducted distrotion in image and change in SUV according to substance with GEMINI TF PET/CT of Philips.. SUV for materials resulted in 1.8 for stainless, 1.4 for stent, 2.4 for iodine contrast medium, 2.6 for Barium Sulfate, 1.6 for Gypsum, and 1.4 for paraffin respectively. The distortion of image was remarkable for the iodine contrast medium and Barium Sulfate. For the barium sulfate, the higher the density, the larger the distrotion of the images. As a result of test, it appeared that the metallic substance whose atomic number is low and contrast medium whose concentration is low didn't affect the distortion in image and the change in SUV. However, it tis necessary to minimize distortion in image and change in SUV, by removing the metallic substance and checking if there are contrast mdeium or before examination.

The purpose of this study was to investigate the effect of dual task training on postural stability and balance in chronic stroke patients. A total of 25 ambulatory hemiplegic stroke patients were recruited into this study and randomly assigned into two groups, the dual task training group (n=13) and control group (n=12). Both groups received general physical therapy for 30 minutes a day, 5 days a week during 6 weeks. In addition, dual task training group received dual task training programs for 50 minutes a day, 3 days a week during 6 weeks. The scores of Trunk Impairment Scale (TIS), Postural Assessment Scale for Stroke (PASS) and postural sway with eye opened and eye closed on the Force Plate were assessed before and after intervention. Postural stability and balance significantly improved after training in the dual task training group(p<0.05). The result suggests that dual task training is feasible and suitable for individual with chronic stroke.

PURPOSE: The purpose of this study was to systematically analyze the reliability and validity of the Korean-version of the balance assessment tools. METHODS: Two reviewers of this study independently evaluated the titles of articles and abstracts of studies published until December 2016 through electronic databases (RISS, NDSL, KISS, DBpia) using the keywords "Balance or posture or postural control or postural stability", "Test or assessment or measurement or outcome measure or assessment tool or measurement tool", "Korean version", "Reliability" and "Validity". Regarding the questions considered suitable for the purpose of this study, consensus was reached after reading the full text. Selecting journals suitable for the purpose of the study, they were analyzed as data. RESULTS: The reviewers selected nine papers suitable for the purpose of this study, and Korean-version of the balance assessment tools, included the Berg Balance Scale (BBS), Activities-specific Balance Confidence (ABC) scale, Postural Assessment Scale for Stroke (PASS), Motor Assessment Scale (MAS), Trunk Impairment Scale (TIS), Falls Efficacy Scale (FES), Tinetti-Balance scale, Fullerton Advanced Balance (FAB) scale, and Function In Sitting Test (FIST). Our study showed that the reliability and validity of the Korean-version of the balance assessment tools were high. CONCLUSION: The Korean-version of the balance assessment tools with high reliability and validity would enable physical therapists to make a more accurate evaluation of balance.

This study examined the effects of pearling, simple heating, baking and extrusion in processing of barley contaminated with deoxynivalenol (DON) on the reduction or destruction of DON. The DON contamination level of barley used in the experiment was 2.08 ppm. The DON-forming strain isolated from the barley was Fusarium graminearum, and the DON formation potential of which was 6.3 ppm on the average in Czapek-Dox broth medium. The DON removal efficiency of pearling was 56.5%, simple heating 3.8-32.7%, extrusion 53-59%, and baking 10.4%. As a large quantity of DON still remains after processing, it tis necessary to develop a new method of removing DON comletely.

Through Tourism Information System, we can know, how much we feel importance of travel information and how to they spending, research when they need to go to travel according to we have to realize about anticipation/planning phase and on-site phase are different exactly. This purpose is how to get a basic data when we support with tourist about information of festival in travel and also how to give satisfaction for tourist and how many tourist wants to join the travels in addition, it is possible to we can develop all of things about travel informations. This is a result of research. First, all of the tourists participate the FESTIVAL, even though they didn't get any informations about travel. The second, information of festival in travel has different feeling between importance of participate in festival and performance after experience.

PI201232, a pepper line resistant to Phytophthora capsici Leonian, was crossed with PI2713222 and P1163192, resistant to Xanthomonas campestTis pv. vesicatoria (Doidge) Dye and inheritance of the resistance to each disease and genetic relationship between the two disease resistances was studied. Non-hypersensitive resistance to race 3 of X. c. pv. vesicatoria of PI271322 was inherited in a quantitative mode. Resitance to P. capsici of PI201232 was inherited in a mode close to two dominant alleles. Hypersensitive resistance to race 1 of X. c. pv. vesicatoria of PI271322 was inherited in a mode of single dominant allele. PI 163192 was consistently resistant to both race 1 and race 3 of X c. pv. vesicatoria and the resistance was inherited in a quantitative mode with high dominance effect. Resistance to X. c. pv. vesicatoria was inherited independently from resistance to P. capsici.

To confirm the food quality and storage stability of commercial Korean kamaboko, we experimented with the composition and textural properties using various surimis and kamaboko products. We also investigated changes in protein digestibility and lipid oxidation of vacuum packed products under chilled storage at $4{\pm}1^{\circ}C$. Among the fish meatbased surimi, vegetable mixed surimi had the lowest protein content (23.73 %), as compared to other surimi (51.9-73.6%). Siginificant (P<0.05) differences in protein, lipid content and degree of fat oxidation were noted between the fried kamaboko products of three companies. Adhesiveness, springiness, cohesiveness, gumminess, chewiness and resilience were similar in all samples, but there were notable differences in hardness and fractuability between samples. In vitro protein digestibility and trypsin indigestible substrate (TIS) were not inversely proportional in fried kamaboko products. The protein digestibility (80.30%) of steamed vegetable mixed fried kamaboko was lower than that of other fried samples (84.9-86.2%). Computed protein efficiency ratio (C-PER) of companies A and C's fried kamaboko was 2.6 but company B's was 1.9. There was no noticeable change in thiobarbituric acid reactive substances (TBARs) or protein digestibility for any of the vacuum packed fried kamaboko during 30 days of chilled storage.

Prior to the study of the sewage treatment methods, water quality for Gwangju sewage of fluent was investigated from January to December, 2004 for sewage water reuse. Monthly mean values of BOD, SS, turbidity, total phosphorus and color were 4.1 mg/L, 2.9 mg/L, 0.8 NTU, 1.3 mg/L, and 27 unit, respectively. Jar-test was performed to investigate the removal efficiency of pollutants under the coagulation conditions of fast mixing for 5 min, slow mixing for 15 min and precipitation for 1hr. Here, alum and polyaluminium chloride (PAC) were used as coagulants to reduce color, turbidity, total phosphorus (TP) and total organic carbon (TOC) in sewage effluents. The results showed that PAC gave better efficiency in removing turbidity and dissolved phosphorus than alum. It was also found from the relative molecular weight (RMW) distribution analysis that organic matter over 1,000 Dalton (Da) was easily removed by coagulation and subsequently MF treatment, while it was not effective for less than 500 Da. Based on tis result, Natural organic matter (NOM) with lower molecular weight (< 500 Da) may cause harmful disinfectant by-product (DBP) after chlorine treatment. Thus, activated carbon adsorption seems to be required for the complete removal of DBP in the hybrid system.

Historical Documents on Proper Tree Selection System of Korea were collected in Japan and introduced in this review. Products of some pine species and fruit were used for laying a tribute to Kings in the Chosun dynasty. In this review, some case studies and implementation of proper tree selection system during the period of Japanese rule, the atlas of climatically favourable regions for the species of trees and bamboos in Korean peninsular, and the test results on regional afforestation, tree selection and proper tree selection of fast growing trees were introduced. Of these documents, especially, the atlas of climatically favourable regions of trees and bamboos growing in Korean peninsular is considered as a valuable document. It tis expected that these historical documents on proper tree selection system might be use as references for the researches on indigenous forest, forest resources development, afforestation of fire damaged areas, and the restoration project of North Korea by the time of reunification of Korea.
