The purpose of this study is to investigate the dyeability of crabyon fiber contained cotton towels after dyeing with gallut. In this study, the colorants of gallnut were extracted with boiling water at 60 o C and 60min. Crabyon, composite fiber of Chitin/Chitosan and cellulose, is manufactured by uniformly blending Chitin/Chitosan and cellulose viscose and extruding the blended viscose into spin-bath. Cotton towels with crabyon fiber dyed with extracted solution from gallnut according to concentration, temperature and time. Crabyon fiber contained cotton towels dyed using gallnut were pre of post-mordanted using Al, Cu, and Fe. The dyeability(K/S) and color characteristics(L * , a * , b * , C, and h(color angle)) of dyed crabyon fiber contained cotton towels were measured by computer color matching machine and photographs. The crabyon fiber composition of cotton towels was conformed by amide peak(-CONH-) of chitin or chitosan of FT-IR spectroscopy. The results obtained were as follows; The amide peak of crabyon fiber contained cotton towels appeared at about 1652 cm -1 . The dyeability of crabyon fiber contained cotton towel was increased gradually with increasing concentration of gallnut dyeing solution and saturated at about 150%(o.w.f). The optimum dyeing temperature and dyeing time were 90~100 o C and 80minutes expectively. The crabyon fiber contained cotton towels were dyed reddish yellow by non, Al, and Cu mordanting, reddish blue by Fe mordanting, respectively. The fastness to washing according to concentration of gallnut in and mordanting method indicated good grade result as more than 3~4 degree in all conditions.

Objective: The objective of this study was to examine the effects of concentrative and spacing repetitions on language, number, and temporal memory of mentally retarded children. Method: Forty children with mental retardation who received occupational therapy at J hospital and H center located in Seoul from June to September 2012 were equally divided into a concentrative repetition training group and a spacing repetition training group. In order to look at their cognitive function, verbal memory, number memory, and temporal-spatial memory, Lowenstein occupational therapy cognition assessment (LOTCA), Hopkins verbal learning test (HVLT), digit span test (DST), and Rey-Osterrich complex figure test (ROCF), respectively, were conducted prior to and after the experiment. Results: In comparison within each group, there was significant difference between prior to and after LOTCA in both group (p<.05) and there was no significant difference between prior to and after temporal-spatial memory evaluation in both groups. In comparison between the two groups, there was significant improvement in the spacing training group in delayed recall among HVLT and backward memorizing among DST relative to the concentrative training group (p<.05). Conclusion: Spacing training is more effective than concentrative training as an efficient training method for the improvement of memory in mentally retarded children.

본 연구는 경기남부지역의 일반음식점과 김밥전문음식점으로 나누어 제조단계에 있는 김밥과 김밥의 원료를 대상으로 하여 총호기성균 오염도 분석결과, 김, 단무지, 햄에서만 차이를 보였을 뿐 전반적으로 $5-6 log_{10}CFU/g$ 수준으로 통계적인 유의 차는 없었다(p>0.05). 대장균군(coliforms)의 경우도 계란에서만 차이를 보였을 뿐 일반음식점과 김밥전문음식점의 오염수준은 $4 log_{10}CFU/g$ 수준으로 유의차가 없었다(p>0.05). E. coli는 일반음식점에서 65% 검출빈도에 $0.7-2.6 log_{10}CFU/g$ 수준의 오염을 보여 8.33% 검출빈도에 $0.70 log_{10}CFU/g$수준의 오염을 보인 김밥전문음식점 보다 유의적으로 높은 검출율을 보였다. S. aureus는 단무지를 제외한 모든 원료, 즉 밥, 김, 햄, 계란, 오이, 우엉, 당근, 게맛살에서 $0.21-5.88 log_{10}CFU/g$수준에서 20100% 빈도로 검출되었으며 일반음식점과 김밥전문음식점간의 유의차는 없었다(p>0.05). B. cereus는 김밥 중 17-20% 빈도에 $0.7-3.4 log_{10}CFU/g$수준의 오염을 보였으며, 일반음식점과 김밥 전문음식점간의 유의차는 없었다(p>0.05). L. monocytogenes는 모든 김밥과 원료에서 전혀 검출되지 않았다. 전반적으로 경기도 남부지역에서 제조된 김밥과 그 원료에 대한 위생수준은 상당히 불량한 것으로 판단되어지며, 본 연구에서 밝혀진 식중독균의 정량적 분석자료는 미생물위해평가(MRA)의 기초자료로 활용될 수 있다. Contamination levels of total aerobic bacteria, coliforms, Esherichia coli, Staphylococcus aureus, Bacillus cereus, and Listeria monocytogenes of Kimbab and its main ingredients sampled from general and specialized restaurants were compared. Total aerobic bacteria and coliform counts of Kimbab samples from both restaurant types were not significantly different (p>0.05), showing approximately $4\;to\;6\;log_{10}CFU/g$. E. coli counts were significantly higher in kimbab from general restaurants ($65%:\;0.7-2.6\;log_{10}CFU/g$) than those from specialized ones ($8.33%:\;0.70log_{10}CFU/g$), whereas those of S. aureus and B. cereus were not significantly different (p>0.05). L. monocytogenes was not detected in all Kimbab samples. These results indicate hygiene of Kimbab and its main ingredients are deleterious. Contamination levels of pathogens determined in the present study may be used as primary data for microbial risk assessment.

Objective: The purpose of this study was to restore the balance of the whole body and resolve cervical spine problems, such as cervical curve deformity, by applying cervico-lumbar exercises in cervical spine patients. Method: Twenty-seven patients with 5° or larger cervical curve deviations were selected from patients at T Hospital and were randomly divided into a cervical exercise group and a cervico-lumbar exercise group. The cervical curves, including the cervical lordotic angle, thoracic kypotic angle, lumbar lordotic angle, and Ferguson angle, of both groups were measured using X-rays. The values of body alignment, including the ear, acromion, great trochanter, lateral epicondyle of the knee joint, and malleous, were measured using dynamic posturography. Eight weeks after the measurements, both groups were re-measured to compare the results before and after the experiment. Paired t-tests and an ANCOVA were employed to analyze differences in the averages of the two groups and to perform a comparative analysis with the experimental phase. Results: The within-group comparison showed that both groups had statistically significant changes in the cervical lordotic angle before and after the experiment(p<.05). Regarding the values of body alignment, the control group showed no statistically significant changes in the ear, acromion, and great trochanter(p<.05), whereas the test group exhibited statistically significant changes in the same variables. Conclusion: In this study of cervical spine patients, the application of cervico-lumbar exercises was more effective than cervical exercises.

Objective: This study examined how trunk exercise on the ball and trunk exercise on the mat influence the sitting postural control in children with cerebral palsy. Method: This study divided 24 children with cerebral palsy, who received pediatric physical therapy at Hospital C located in Gyeonggi-do from June to September, 2012, into each group of 12 children and applied ball trunk exercise and mat trunk exercise to the two groups respectively for a six-week period with two times each week and 30 minutes each time. In order to identify their sitting postural control function, the K-GMFM (Korean version of Gross Motor Function Measure), AIMS (Alberta Infant Motor Scale), and SEMG (Surface Electromyography) were measured before and after the training. Result: In comparing within each group, the two groups exhibited statistically significant differences (p<.05) before and after the training in all the measurements of K-GMFM, AIMS, and SEMG. When the two groups were compared, the AIMS showed no statistically significant differences. However, in the K-GMFM and the right-side abdominal muscles in the SEMG, the two groups revealed statistically significant differences (p<.05). Conclusion: Ball trunk exercise and mat trunk exercise were both effective training methods for the sitting postural control in children with cerebral palsy. However, ball trunk exercise was found to be a more effective method.
