This study was performed to search for correlation between activity limitation level and participation restriction of children with cerebral palsy by investigating the activity limitation level through the use of the GMFCS E&R and the MACS and by figuring out participation restriction level through questionnaire survey. This study was performed, from May 1, 2010 to August 31, 2010, on 152 children with cerebral palsy ranging from 4 to 12 years, who are receiving rehabilitation therapy in the hospitals and community clinics in Busan and Gyeongnam province. The levels of activity limitation were assessed by using GMFCS E&R and MACS, and a questionnaire survey was conducted for participation restriction of the participating children. Spearman rank correlation was used for correlation analysis with the statistical software, SPSS 12.0. Majority of the children scored level 5 in both GMFCS E&R and MACS which is high frequency of activity limitation levels. Children in these levels also showed severe or complete participation restriction for mobility, education, and social relations. The analysis showed a significantly positive correlation between activity limitation level and participation restriction. Therefore this study may be useful in assessing the functional movement component of participation in children with cerebral palsy and developing the intervention plan for participation.

About thirty bacterial strains of actinomycete isolated from the soil were examined for the presence of restriction endonuclease activity. Streptomyces diastatochromogenes, which was identified previously, was found to contain restriction endonuclease activity. The purification of this enzyme, SdiI, was carried out via streptomycin sulfate precipitation and ammonium sulfate fractionation followed by hydroxylapatite column chromatography. Sephacryl S-200 HR column chromatography and second hydroxylapatite column chromatography. SDS-polyacrylamide gel electrophoresis of the active protein (purified from various column chromatography) resulted in 35,000 Da protein.

The purpose of this research is to elucidate the analysis on leisure viewpoint of immigrant female of multi-cultural families. This survey research have been performed with 140 of immigrant females who participate to the program of multi-cultural families support center located in Kyungki-do, Taejeon city, Chungnam-do and Chungbuk-do in 2010 by purposive sampling method. The final analysis was obtained from the survey results of total 89 immigrant females and the credibility of this survey represented Cronbach's ${\alpha}$ value above .613. The apparent results were the follows: First, the major leisure time of immigrant females of multi-cultural families on week days as well as weekend represented to be 1~2 hours. Second, the satisfaction on leisure activity of immigrant females was average level. Third, the best preference as leisure activity was travel. Fourth, their husbands were the favor partner for leisure activity of immigrant females. Fifth, the restriction on leisure activity of immigrant females showed some differences based on age, academic background, nationality and residence period. That is, personal restriction of age was below 25 years old, the highest personal and relative restriction of academic background represented in immigrant females below middle school graduator. Furthemore, the structural restriction and personal restriction on nationality showed the highest in the china and phillippine females, relatively. Personal restriction on residence period was mainly represented in immigrant females residing during 2.1~4 years.

Metabolic responses to the protein-free, high-carbohydrate diet and subsequent food restriction on the same diet at the level of 50% and 75% has been studied on the adult albino rats. The energy source was either corn starch or sugar. In experiment I, adult male rats weighing $509{\pm}8g$ were divided into two groups 10 rats each. Rats fed on the stock diet served as a control. Rats of restriction group received a protein free diet until they reduced their weight down to 400g and continue on a protein-calorie restriction diet until they reduced their weight down to 300g. In experiment II, 28 adult male rats and the same numbers of female rats weighing $329{\pm}5g$ and $223{\pm}4g$ respectively were divided into four groups, 7 males and females in each. Rats fed on a stock diet were sacrificed at the point when others started a protein free diet. These were served as the control. The protein free group received a protein free diet ad libitum for 4 weeks. The 50% restriction group and 75% restriction group were fed on a protein free diet coupled with food restriction at levels of 50% and 75% respectively for 3 weeks. In the result of this study: 1. The rate of body weight changes was similar between the males and the females. Feeding protein free diet ad lib. initiated a rapid weight lost of approximately 25% and protein free diet coupled with food restriction showed 37-43% reduction of their initial weight. 2. There was no significant differences in the value of the N concentration in liver, spleen, brain and muscle between controls and experimental groups. 3. Rats fed on protein free diet showed 1/10 value of the control in the nitrogen excretion in urine. However female showed less N excretion than male. 4. Observing blood picture, the effects of protein depletion and calorie restriction were not appeared any remarkable changes. 5. There was no sign of fatty liver which might result from protein depletion and calorie restriction. 6. Following semi-starvation, FAO and HMP-DH total enzyme activity was reduced, but activity per unit weight was relatively stable.

To determine the effect of dietary fat and calorie level on protein kinase C(PKC) activity in mouse epidermal cells, female BALB/C mice (4weeks of age) were placed on high (24.6% ), moderate(5%) fat or calorie-restricted diets for at least 4 weeks. Diets were formulated on a nutrient/kcal basis such that the mice consumed the same amounts of protein. vitamins, minerals and fiber per kcal. PKC was assayed by the procedure of Wise et at. An apparent increase of PKC activity was observed from the aminal fed high fat diet when compared with the aminal fed moderate fat diet. PKC activity was decreased 40% by calorie restriction. In summary levels of dietary fat may contribute to mechanism of tumor promotion by increasing PKC activity in the mouse skin model.

The gene for the Bdi I modification enzyme, which is one of Bdi I restriction-modification system, fromBrevibacterium divaricatum FERM 5948 was cloned and expressed in E. coli. For cloning of the Bdi I methylase gene, we have initially used three cloning site(EcoRI, BamHI and Sal I) of plasmid vector pBR 322 and adopted the retransformation method after Bdi I restriction endonuclease cleavage. Selection of transformants carrying the gene was based on the resistance of the modified plasmid encoding the enzyme to cleavage by Bdi I restriction enzyme, and the recombinant plasmid pBDIM 116 containing 5.6kb EcoRI insery was proved to carry the gene. Crude cell extracts prepared from strains carrying the plasmid pBDIM 116 contained an S-adenosylmethionine-dependent methyltransferase activity specific for the Bdi I recognition site, ATCGAT. The restriction map was constructed with 11 restriction enzyme, and the Bdi I restriction-modification system was also discussed.

The objectives of this study were to examine calpain activity and meat tenderness by three different feeding patterns in Korean native cattle (KNC). Total forty-five animals were assigned each fifteen in long term restriction feeding (LTFR), long-term restriction feeding and hormone treatment (LTFR-tH), and short term non-restriction feeding (STFNR), respectively. Concentrate was restricted based on body weight in exp 1 and 2. However, it was fed ad libitum in exp. 3. Hormonal implantation was made with $M-PO^{TM}$ for bulls and with $F-TO^{TM}$ for heifers at 18, 20, 22 months of age in exp. 2. Animals were purchased (3-5 month old) from local cattle market and managed in two local farms and university research unit at three different years. Animals were slaughtered at 24 months for long-term trial and at 18 month for short term-trial. Loin and tender loin muscle was used for calpain activity and meat quality. Calpain proteolytic system was not changed by treatment. However, calpastatin activity was low in short-term trial. The calpain and calpastatin activity is reciprocal relationship, therefore, the high calpain activity may effect on quality grade. The shear force value was decreased as the processing of aging after postmortem. On the other hand, the cooking loss was significantly higher in short-term than in long-term trial, and then gradually decreased by the aging. Hormone implants to increase meat yield influenced to calpastatin activity more powerfully than calpain activity to meat tenderness. In meat color-a*, there was not significant difference in loin. Meat color-b* was decreased as postmortem aging time increased in tenderloin. Western blots were done to learn whether these proteins are degraded during postmortem storage and whether this degradation temporally parallels the decrease of shear force value. Vinculin was detected at 0 day and 1 day and degraded after 3 day. In conclusion, Calpain activity was affected slightly on meat tenderness. But meat tenderness was influenced by calpastatin, more effectively.

It has been known that Ganoderma lucidum and Lentinus edodes have anticancer activity and immune enhancing activity. These two mushrooms were grown in liquid culture and harvested. From these mycelia, DNA was isolated and EtBr-CsCl density gradient ultracentrifugation was performed to purify it further. Then mitochondrial DNA was isolated by bisbenzimide-CsCl density ultracentrifugaton. Mitochondrial DNA of Ganoderma lucidum was digested by restriction enzymes, EcoR I, Hind Ⅲ, and Pst I, then electrophoresed. It showed 12, 22, 4 fragments. Mitochondrial DNA of Lentinus edodes was digested by EcoR I. Electric pattern showed 6 fragments. 4 fragments had appeared by Pst 1 digested mitochondrial DNA. Hind ill couldn't digest mitochondrial DNA of Lentinus edodes. Mitochondrial DNA of fusants was isolated to compare to those of parents. The results showed that fusant P₂S₄has new, recombined mitochondrial DNA. But P₂S₄had the same DNA that Ganoderma lucidum had.

A genomic library of a mesophilic cellulolytic anaerobe, Clostridium sp. KCTC 8440 DNA was constructed in Escherichia coli using plasmid pUC9. Clones of E. coli exhibiting carboxymethyl cellulose-hydrolyzing activity (CMCase) were isolated and divided into seven types based on the restriction enzyme patterns of recombinant plasmids. E. coli strains carrying type A genes showed activity on carboxymethyl cellulose about 7-8 times greater than clones carrying genes of other types. Restriction maps of the cloned DNA fragments were determined, and homologies between them were investigated. The results suggest that Clostridium sp. KCTC 8440 has seven distinct CMCase genes.
