Both cardiovascular diseases caused by decreased body composition and arterial compliance and falling induced by loss of muscle mass are frequent occurrences in the elderly. Therefore, elderly people are advised to perform elastic band resistance exercises to improve their body composition and arterial compliance. Thus, the purpose of this study was to examine the effects of 12 weeks of elastic band resistance training on the body composition, arterial compliance and falling index in elderly females (> 65 years). The elastic band resistance exercise program was administered 3 times per week for 60 minutes each time for 12 weeks. In addition, the exercise intensity was set to 11-14 on the Borg scale (6-20). Before and after the training period, the body composition (body weight (BW), muscle mass, % body fat, body mass index (BMI)), arterial compliance (ankle brachial index (ABI) and pulse wave velocity (PWV)) and risk of falling index were determined. (After the program?), the BW (p=.003), BMI (p=.002), PWV (p=.017) and risk of falling (p=.037) in the exercise group were significantly reduced, whereas the BW (p=.009) and BMI (p=.009) in the control group were significantly increased. In conclusion, the body weight, BMI and arterial compliance of elderly females were positively changed by the elastic band resistance training. Thus, the elastic band resistance exercise may be useful for elderly people to prevent metabolic syndrome and cardiovascular diseases and to reduce their risk of falling.

The purpose of this study was to evaluate the effects of barley cultivars (Saessalbori, Saechalssalbori and Huinchalssalbori) and different milling recovery (95%, 85% and 75%) on quality characteristics of barley Makgeolli. The content of moisture, ash, crude protein, and crude fat in barley seeds were reduced with decreasing milling recovery. The qualities of barley Makgeolli were also significantly affected by the milling recovery. Decreasing milling recovery of all cultivars resulted to increase in total sugar content and reducing sugar content but decrease in pH while alcohol content and total acidity were not significantly affected. Moreover, the lightness and yellowness of barley Makgeolli increased by milling while its redness decreased. The sensory evaluation showed that the consumer preference for barley Makgeolli increased at the lowest milling recovery (75%). The results of this study suggest that the milling recovery and cultivar of barley were important factors to improve the taste and color of barley Makgeolli.

This study was carried out to investigate the effects of dietary tocotrienol extracted from the rice bran on hematological and histological changes of the mouse. The mice were divided into seven groups (basal diet, cholesterol diet, tocopherol diet, and 4 different tocotrienol diets), and bred for a month. Tocotrienol diet was shown to have decreasing effects of serum triacylglycerol and LDL concentrations, whereas serum HDL concentrations were increased by tocotrienol diet. But serum cholesterol concentration was not statistically significant among the diet groups. Tocotrienol diet was shown to have decreasing effects of serum AST activities (P=0.0548) and LDH activities (P=0.0016), which are the standard indicators for liver damages or myocardial infarction. And tocotrienol diet has reduced the fat bodies accumulated in liver and heart caused from administration of rice bran oil. Also, the effects were shown as concentration-dependent manners. In conclusion, dietary tocotrienol extracted from rice bran has evident effects to protect or reduce lipid accumulation from blood, hepatocytes and heart muscles. It is also suggested as a good fortifying nutrition for the health and medical care.

This study investigated the effects of superheated steam (SHS) and high hydrostatic pressure (HHP) on the quality of Galbijjim. SHS cooking increased moisture and crude fat contents and decreased crude protein contents (P<0.05). The value of L was significantly higher upon SHS cooking compared to conventional cooking (CC), whereas a and b values were not significantly different among the samples. Hardness decreased more upon CC than SHS. The results of the safety storage experiment at refrigeration temperature showed that the total number of bacteria was lower in SHS-HHP than in CC-HHP. The thiobarbituric acid value increased to 0.70~1.56 mg malonaldehyde (MA)/kg in CC-HHP after 15 days, and SHS-HHP showed 0.69 (0 day)~1.24 (15 days, $10^{\circ}C$) mg MA/kg. Volatile basic nitrogen value was 18.07~36.76 mg% in CC-HHP, and that in SHS-HHP also increased to 17.06 (0 day)~35.76 mg% (15 days, $10^{\circ}C$). Overall, SHS cooking and HHP reduced microorganisms, which could improve product quality and sanitation.

In present study possible hypolipidemic effects of garlic were investigated in an experimental model which consisted of 4 groups of Wistar rats(three weeks old): CO group received a basal diet(as a standard diet) contained 6.3% of corn oil. LO group was taken the experimental diet in which only 6.3% corn oil in basal diet was substituted by 12.6% of lard oil. So the experimental diet was somewhat high saturated fat diet. LG1 group was treated orally with garlic juice as 1% of raw garlic in the diet together with the same diet as the diet for LO group. LG2 group was taken 2% of garlic under the same dietary condition as that of LG1 group. The rat body weights prior and posterior to the experimental period were measured and the amount of the experimental dietary intake was determined at every 3 day interval. After the experimental dietary period of 30 days the blood obtained from all the sacrificed rats were analyzed for the biochemical parameters. Over the one month period of experiment there was no abnormality or apparent change in appearance and activity or diet consumption in all experimental rat groups. LO group fed a diet rich in lard showed significantly increased body weight gain rate by 30% and also elevated levels of triglyceride, total cholesterol and LDL cholesterol by 29.9%, 27.4% and 62.3% respectively and no significant difference in the levels of HDL cholesterol, GOT, GPT, blood glucose and blood urea nitrogen as compared to those of control group. So it seemed that the high calorie diet in LO group mainly contributed to the significant increase in body weight gain rate and other biochemical parameters. In spite of 1% garlic treatment LG1 group had significantly increased body weight gain rate by 25.2%, levels of triglyceride, total choesterol and LDL cholesterol by 25.2%, 24.6% and 50.5% respectively as compared to control and LO group, and no increase in the levels of HDL cholesterol, blood glucose and blood urea nitrogen. At garlic 1% diet there was no hypolipidemic efficacy in rat serum. Under the treatment with garlic 2% in diet LG2 group showed significantly increased body weight gain rate by 19.7% as compared to control and elevated levels of GOT, GPT and BUN by 85.8~96.4%, 127~148% and 88% respectively as compared to control, but LG2 group had significantly reduced levels of triglyceride, total cholesterol and LDL cholesterol as compared to LOand LG1 group. In present study there were no significant change in HDL cholesterol and blood glucose value. In LG2 group GOT, GPT and blood urea nitrogen values were slightly increased presumably due to the inhibiting effects of garlic on the hepatic or renal function of rats. Nevertheless in this study garlic may have some demonstrable hypolipidemic effects in rat.

The purpose of this study was to compare the circumference, skinfold thickness and strength of the normal and casted lower limb prior to casting and following removal of the cast. The subjects for the study were nine orthopedic patients who had had long and short leg casts due to a tibial, fibula, or calcaneus fracture, or to a lateral collateral ligament rupture. Circumference, skinfold thickness, and strength of the normal and casted lower limb following removal of the cast were compared with those prior to the application of the cast. Measurements were made before cast application and after removal of the cast. Skinfold thickness was measured by fat caliper, circumference was measured by tape and strength was determined by measuring the length of time the leg was held elevated at 45$^{\circ}$. The results can be summarized as follows 1. There was no change in the normal limb in the circumference of the midthigh and midcalf after casting as compared to before cast application. 2. In the casted limb the circumference of the midthigh decreased by 3.23% and that of the midcalf decreased significantly by 7.49% during the period of casting. 3. In the normal limb skinfold thickness of the quadriceps decreased and that of gastrocnemius increased by 20.63% during the period of cast application. 4. In the casted limb skinfold thickness of the quadriceps decreased significantly by 12.37% and that of gastrocnemius decreased by 10% during the period of cast application. 5. Strength of the normal lower extremity decreased significantly by 48.37% and that of casted lower extremity decreased remarkably by 73.07% during the period of cast application. 6. Circumference of the midthigh and the midcalf decreased significantly by 7.6% and 9.4% respectively on the casted side as compared to the normal side. Skinfold thickness of the quadriceps and the gastrocnemius on the casted side decreased by 6.12% and 18.55% respectively as compared to the normal side and strength in the lower extremity on the casted side decreased significantly by 44.32% as compared to the nor-mal side. From these results, it may be concluded that muscle atrophy occurs in the casted lower limb and muscle strength of the normal lower limb are also reduced during the period of application of a leg cast.

The obesity is a medical condition in which excess body fat has accumulated to the extent. It may have an adverse effect on health, leading to reduced life expectancy and increased health problems such as lifestyle disease, hypertension, and diabetes. Furthermore, it may cause the mental illness such as depression, bipolar disorder, anorexia, hyperphagia, and so on by shrinking psychologically. So, it is regarded as the serious worldwide social problem. Recently, although there are many general obesity care methods with various approaches, these can't be the radical obesity care because of the side effects such as surgery aftereffect, drug addiction, and so on. For these reasons, a methodical approach with a consideration of individual obesity pattern is strongly demanded. In this study, complex obesity care and management system which is overcome the weakness of non-surgical obesity treatment is proposed. And the individually adapted obesity treatment system with the far-infrared therapy module, oxygen therapy module, color therapy module, and microwave therapy module was developed. The complex obesity treatment system which is proposed in this study, could improve the efficiency of treatment by suggesting the various treatment protocols. And proposed system could be the foundation of the high quality obesity treatment system.

In this study, Tenebrio molitor (brown mealworm) larvae powder was fermented with Saccharomyces cerevisiae M1 (KACC 93023). The fermented and non-fermented powders were subsequently administered to rats with induced non-alcoholic fatty liver disease to compare the degree of improvement. The rats exhibited abnormal lipid metabolism due to orotic acid, and the group that were fed the fermented larvae powder showed similar weight to normal rats. AST, ALT, ALP, and LDH activities, all known indicators of liver health, and various other lipid-related indicators appeared positive, suggesting improvement. The lipid peroxide and glutathione content in the liver tissue and serum were similar to or better than those of the normal group. Finally, morphological observations of liver tissue using H&E and oil red O stainings revealed that the fermented powder group showed markedly reduced fat along with normal hepatocyte shape and arrangement. To summarize, it was confirmed that dietary brown mealworm larvae improve non-alcoholic fatty liver function, and, when fermented with yeast, most indicators showed positive improvements to almost normal levels. As such, the fermented powder can be considered to improve non-alcoholic fatty liver, suggesting that it may be used as a material for various products in the future.

In order to improve wine quality, the selection of yeast strain and of additives in the manufacture of Bokbunja (Rubus coreanus Miq.) wine was investigated. The chemical composition of the edible portions of Bokbunja fruits was 86.5% moisture, 0.2% crude protein, 0.9% crude fat, 6.6% crude fiber, 0.5% ash and $10^{\circ}Brix$ sugar, and was 2.99% fructose, 2.53% glucose and 0.07% sucrose in fruit extract. The predominant organic acids in the fruit were citric acid (14.57 mg/mL) and malic acid (2.24 mg/mL) with smaller amounts of shikimic, pyroglutamic and oxalic acid. During fermentation, citric and malic acid levels decreased, while formic and acetic acid were released. Saccharomyces cerevisiae KCCM 12224 (Sc-24) was more favorable for alcoholic fermentation of Bokbunja and the addition of 200 ppm of potassium metabisulphite to must was more efficient than other $SO_2$ sources with a higher overall acceptability score. Sc-24 increased alcohol production from 9.8 to 14.8% in a sugar concentration dependent manner $(18-28^{\circ}Brix)$. The color value of early stage Bokbunja must was improved by supplementing with Japanese apricot extract, but this did not influence the color value of Bokbunja wine after primary fermentation. The astringent taste of Bokbunja wine was reduced by removing the seed from the fruit. Sugar solution (50%, w/v) was used instead of sugar power to prevent the possibility of undissolved sugar due to insufficient mixing. This substitution did not influence sensory evaluation.

A repeated $4{\times}4$ Latin square design was conducted with eight ileal cannulated castrates to examine the effect of source of starch and fiber on nutrient balance and energy metabolism. Pigs were fed on one of the four experimental diets: Control diet (C) mainly based on cooked rice; and diets P, S and W with the inclusion of either raw potato starch, sugar beet pulp or wheat bran supplementation, respectively. With the exception of an increased (p<0.05) energy loss from methane production with diet S observed, no significant differences (p>0.05) in the ratio of metabolizable energy (ME)/digestible energy, the utilization of ME for fat deposition and for protein deposition, energy loss as hydrogen and urinary energy were found between diets. The efficiency of utilization of ME for maintenance was lower (p<0.05) with diets P and S than with diet C. The inclusion of fiber sources (sugar beet pulp or wheat bran) or potato starch reduced the maintenance energy requirement. The fecal energy excretion was increased (p<0.05) with either sugar beet pulp or wheat bran supplementation, while it was unaffected (p>0.05) by addition of potato starch. In comparison with diets C and P, a lowered ileal or fecal digestibility of energy with diets S and W was observed (p<0.05). Feeding sugar beet pulp caused increased (p<0.05) daily production of methane and carbon dioxide and consequently increased energy losses from methane and carbon dioxide production, while it did not influence the daily hydrogen production (p>0.05). An increased (p<0.05) proportion of NSP excreted in feces was seen by the supplementation of wheat bran. Higher NSP intake caused an increased daily amount of NSP in the ileum, but the ileal NSP proportion as a percentage of NSP intake was unaffected by diets. Feeding potato starch resulted in increased daily amount of starch measured in the ileum and the proportion of ileal starch as a percentage of starch intake, while no significant influence on fecal starch was found. Higher (p<0.05) daily amount of fecal starch and the proportion of fecal starch as a percentage of starch intake were found with fiber sources supplementation compared with diets C and P. By increasing the dietary NSP content the fecal amount of starch increased (p<0.01).
