Cooking is the final production stage of the food industry and is an essential part to define the distinctive feature. Consumers do not want to change their cooking styles because hey team the cooking styles as practices and customs from their region or their ancestor and they are skilled in their use. Corpulence is a major health concern in developed countries and developing countries alike. This study was conducted to suggest the arts of cooking for pork cutlet, a typical dish cooked by batter-fried food, and to decrease the intake of fat and calories. As a result, the fat contents of pork cutlet were lower (p<0.05) than when it was conducted with frying and oven baking. Especially, the pork cutlet cooked by oven baking showed a $10\%$ reduction in calories (p<0.05) compared to frying. The organic functional tests were satisfactory, and oven baking will help people who need dietary treatment.

To develop the high quality gluten-free rice products with health functionality and desirable texture with moistness, the physicochemical properties of extruded rice flours prepared from the mixture of germinated brown and white rices were investigated. The domestic organic Samgwangbyeo was used to make white and germinated brown rices. White rice (WR) was dried after soaked for 6 h at $15{\pm}3^{\circ}C$ and mixed with germinated brown rice (GBR) with different mixing ratios (100:0, 75:25, 50:50, 25:75, 0:100). The operating conditions of twin screw extruder were 250 rpm of screw speed, $120^{\circ}C$ of barrel temperature, and 25% moisture content of rice flour. The ash, crude protein and crude lipid contents were significantly different (p<0.05) and those of extruded GBR were the highest values, but those of extruded WR were the lowest. The color difference of extruded WR based on white plate showed the lowest among them. The water binding capacity (334.16%), swelling power (8.83 g/g), solubility (33.13%), and total starch (79.50%) were the lowest in extruded GBR. The viscosities of all extruded rice flours by RVA were maintained during heating. The peak and total setback viscosities of extruded rice flours ranged 127-352 and 58.0-85.5 cP, respectively. The novel food biomaterial from germinated brown rice as well as white rice was developed by twin screw extruder. The extruded rice flours control the moistness to improve the texture and also have functional materials, dietary fiber, GABA, and ferulic acid, etc to increase quality of gluten free rice products.

Objective: The purpose of this study was to evaluate the effect of virtual reality (VR)-based core stabilization exercise on upper extremity function, postural control, and depression among persons with stroke with hemiplegia. Design: Randomized controlled trial. Methods: This study was conducted with the inclusion of 24 participants and were randomly assigned to either the VR-based trunk stability exercise group (n=12) or control group (n=12). The VR-based trunk stability exercise group performed core stabilization exercises in a VR environment for 30 minutes. Meanwhile, the control group conducted general core stabilization exercises for 30 minutes. The participants trained 3 times a week for 4 weeks. The manual functional test (MFT), Box and Block Test (BBT), Berg Balance Scale (BBS), Trunk Impairment Scale (TIS), the Geriatric Depression Scale (GDS) were used to assess all participants before and after the intervention. Results: The VR-based core stabilization exercise group had a significant improvement in upper extremity function (MFT, BBT) and postural control (BBS) compared with the control group (p<0.05). The VR-based core stabilization exercise showed a significant difference after intervention in the TIS and GDS scores (p<0.05), but they did not significantly differ between the two groups. Conclusions: The result showed that VR-based core stabilization exercise can be effective in improving upper extremity function and postural control among patients with stroke more than the sole application of general physical therapy.

PURPOSE: This study aimed to investigate the effects of pressure sense perception training (PSPT) on various surfaces on the somatosensory system, balance, and walking ability in chronic stroke patients. METHODS: Thirty patients with stroke participated in this study and were randomly assigned to one of three groups; group 1 received the general physical therapy and the PSPT on a stable surface, group 2 received the general physical therapy and the PSPT on an unstable surface, and group 3 received the general physical therapy alone. Participants in group 1 and group 2 underwent 30 min/session, 3 days per week, for 4 weeks. Pressure error (PE) was used to evaluate changes of proprioception. The Balancia, Functional reach test (FRT), and Timed Up and Go (TUG) were used to assess the balance ability, and the 10m Walking Test (10-MWT) was used to assess walking ability. RESULTS: Experimental groups (group 1 and group 2) showed significant differences in PE, FRT, TUG, and 10-MWT compared to the control group (p <0.05). Group 2 (PSPT on an unstable surface) was significantly different in PE, FRT, and 10-MWT from group 1 (p <0.05). No significant differences were observed for other measures. CONCLUSION: Pressure sense perception training on an unstable surface might be a significantly more effective method for improving somatosensory function, balance, and walking ability, than PSPT on a stable surface.

It has been recognized that the hen, like its mammalian counterparts, provides young chicks with antibodies as protection against hostile invaders. This system facilitates the transfer of specific antibodies from serum to egg yolk, and provides a supply of antibodies called immunoglobulin Y(IgY) to the developing embryo and the hatched chick. The protection against pathogens that the relatively immune-incompetent newly hatched chick has, is through transmission of antibodies from the mother via the egg. Egg yolk, therefore, can be loaded with a large amount of IgY against pathogens which can immobilize the existing or invading pathogens during the embryo development or in day-old chicks. Thus, the immunization of laying hens to various pathogens results in production of different antigen-specific IgY in eggs. Egg yolk contains 8∼20 mg of jmmunoglobulins (IgY) per ml or 136∼340 mg per yolk suggesting that more than 30 g of IgY can be obtained from one immunized hen in a year. By immunizing laying hens with antigens and collecting IgY from egg yolk, low cost antibodies at less than $10 per g compared to more than $20,000 per g of mammalian IgG can be obtained. This IgY technology opens new potential market applications in medicine, public health, veterinary medicine and food safety. A broader use of IgY technology could be applied as biological or diagnostic tool, nutraceutical or functional food development, oral-supplementation for prophylaxis, and as pathogen-specific antimicrobial agents for infectious disease control. This paper has emphasized that when IgY-loaded chicken eggs are produced and consumed, the specific antibody binds, immobilizes and consequently reduces or inhibits the growth or colony forming abilities of microbial pathogens. This concept could serve as an alternative agent to replace the use of antibiotics, since today, more and more antibiotics are less effective in the treatment of infections, due to the emergence of drug-resistant bacteria.

Purpose: The aim of this study was to assess the effects of proprioceptive neuromuscular facilitation (PNF) pattern exercise using sprinter and skater on balance and gait in the stroke patients. Methods: Twenty-two subjects were randomly assigned to the experimental group (n=11) and the control group (n=11). The experimental group performed PNF pattern exercise using sprinter and skater for 15 minutes with conventional physical therapy for 35 minutes (matt and gait training for 15 minutes + FES stimulation for 20 minutes), while the control group performed only conventional physical therapy for 50 minutes (matt and gait training for 30 minutes + FES stimulation for 20 minutes). Both groups performed therapeutic interventions for five days per week, for a period of four weeks. Functional Reach Test (FRT) and Berg Balance Scale (BBS) were used for assessment of balance, and Timed-Up and Go test (TUG) was used for testing of gait. Results: The experimental group showed significant improvements in the FRT and the BBS, while the control group did not show significant changes in two measurements. The experimental group also showed significant improvements, however, the control group did not show significant changes in the TUG. In post-values of three measurements, significant differences were observed between the two groups (p<0.05). Conclusion: This study demonstrated that PNF pattern exercise using sprinter and skater may be used to improve balance and gait function in stroke patients. Thus, we suggested that PNF pattern exercise using sprinter and skater would be a therapeutic intervention in stroke rehabilitation.

The present study was carried out to evaluate the antioxidant and anti-inflammatory activities of three extracts (hot water, 50% ethanol and mixed solvent;water, ethanol, butylene glycol, propylene glycol) of dried chestnut, chestnut shell, chestnut leaves and dried chestnut leaves obtained from Castanea crenata tree. When conducted DPPH assay, radical scavenging activity of ethanol extract of chestnut shell was the highest with $IC_{50}$ $10.8{\mu}g/mL$ among four extracts from these parts (p < 0.05). In additional results by the xanthine oxidase assay, antioxidant activity showed that water extract of chestnut leaves showed the highest xanthine oxidase inhibitory activity in the tested extracts (p < 0.05). Futhermore, extracts of chestnut shell and leaves exhibited no cytotoxicity in RAW 264.7 cells (p < 0.05). Also, anti-inflammatory activity by NO assay showed LPS-induced NO was significantly inhibited following treatment with extracts of chestnut shell and leaves of 3mg/mL (p < 0.05). These data suggest that extract of chestnut shell have antioxidant and anti-inflamantory activity including chestnut leaves. Therefore, it is considered that Castanea crenata research range and selection of functional material can broaden chestnut shell to other fractions such as chestnut and chestnut leaves.

Background: Many menopausal women suffer from health problems including metabolic diseases such as dyslipidemia and osteoporosis. Thus they need natural products and functional foods particularly highly nutritional food products, that can help alleviate these diseases. This study was carried out to determine the effect of Drynariae Rhizoma water extract on the lipid and bone metabolism of ovariectomized Sprague-Dawley rats. Methods and Results: The animals were randomly divided into six dietary groups comprising SHAM-operated rats, OVX rats (normal diet), and OVX-DR rats (Drynariae Rhizoma extract). After 8 weeks, plasma, liver, and fat samples were collected to analyze the lipid metabolism, plasma Ca, alkaline phosphatase (ALP), osteocalcin and C-terminal telopeptide (CTx) concentrations, which are biochemical makers of bone metabolism. The left femurs of rats were also collected for histological analyses. OVX counteracted menopause induced body weight gain, as well as increases in triglycerides, total cholesterol, and free fatty acids. The Drynariae Rhizoma group showed low levels of triglycerides, high HDL-cholesterol, and decreased lipogenesis based on activity of the lipid-regulating enzymes (fatty acid synthase and malic enzyme). Decreased serum levels of ALP and osteocalcin were observed in Drynariae Rhizoma group. Conclusions: The results of this study show that Drynariae Rhizoma extract may effectively regulate hyperlipidemia and improve bone density.
