Objective: The purpose of this study was to find the limited patterns of middle-aged women in selective functional movement evaluation and analyze the effects of pattern improvement exercises and general control groups on the Health Risk Appraisal (HRA). Design: Randomized controlled trial. Methods: The 31 subjects were physically healthy middle-aged women aged 40-59 living in Seoul, The subjects were randomly divided into an experimental group and a control group. Forty-three physically healthy women were originally recruited and randomly assigned to either the experimental group (n=22) or the control group (n=21). However, due to lack of participation, a total of seventeen subjects in the exercise group and fourteen subjects in the control group participated in the study. All subjects were tested using Selective Functional Movement Assessment (SFMA) and HRA for the baseline measurement and joined an exercise program of their group for one hour per session, twice a week for four weeks. The experimental group was provided with the corrective exercises and the control group was given the general fitness program. A follow-up test was conducted after eight weeks from the baseline measurement. Results: Both experimental and control group showed significant changes in SFMA and HRA scores (p<0.05). In the experimental group and control groups, the SFMA and HRA showed significant improvement from baseline to 4 weeks (p<0.05). Also, in the experimental group, the SFMA was significantly improved from baseline to 8 weeks (p<0.05). For the experimental group, there was a significant improvement in SFMA after 4 weeks compared to the control group (p<0.05). Conclusions: The corrective exercise in the experimental group had a positive effect on the SFMA score as well as the general squat exercise in the control group. The corrective exercise and general control group had the same positive effect on the HRA score.

To understand the role of intestinal microflora in the biological effect of functional herbs, which have been used in Korea, Japan, and China as traditional medicines, and suggest new bioactive compounds transformed from herbal constituents, the metabolic activities of the functional herb components (ginsenoside Rb1, crocin, amygdalin, geniposide, puerarin, ginsenoside Re, poncirin, hesperidin, glycyrrhizin, and baicalin) toward their bioactive compounds (compound K, crocetin, benzaldehyde, genipin, daidzein, ginsenoside Rh1, ponciretin, hesperetin, 18b-glycyrrhetic acid, and baicalein) were measured in fecal specimens. The metabolic activities of these components were $882.7{\pm}814.5$, $3,938.1{\pm}2,700.8$, $2,375.5{\pm}913.7$, $1,179.4{\pm}795.7$, $24.6{\pm}10.5$, $11.4{\pm}10.8$, $578.8{\pm}206.1$, $1,150.0{\pm}266.1$, $47.3{\pm}58.6$, and $12,253.0{\pm}6,527.6\;{\mu}mol/h/g$, respectively. No differences were found in the metabolic activities of the tested components between males and females, although these metabolic activities between individuals are extensively different. The metabolites of functional herb components showed more potent cytotoxicity against tumor cells than nonmetabolites. These findings suggest that intestinal microflora may activate the pharmacological effect of herbal food and medicines and must be the biocatalytic converter for the transformation of herbal components to bioactive compounds.

The foot performs an important function in supporting the body and keeping body balance. An abnormal walking habit breaks the balance of the human body as well as the normal function of the foot. The influence of a flatfoot(pes planus) occupies a considerable portion of the various causes resulting in the wrong walking habit. But, little studies has been done by the functional foot orthotics for the flat foot. The object of this study, therefore, is to propose a new approach method to reveal the effects of the improvement of the foot function by using orthotics. The essential point of this study is to measure and analyze the change of ankle angle in the sagittal plane for flat foot subjects wearing the orthotics. Before and after wearing the functional orthotics, the gait analysis of flat foot subjects was conducted in three experimental aspects : the change of ankle angle, the change of the total Ankle ROM and the difference of left & right ankle angle in the sagittal plane. 1. The average ankle angle differences of before-and-after wearing the orthotics have declined like this; left : $2.71^{\circ}$, right: $1.91^{\circ}$ (p<0.05). 2. Total ankle ROM also showed decrease in both sides while the left side's is rather slight; left : $0.57^{\circ}$, right : $2.07^{\circ}$ (p<0.05). 3. The difference of left and right ankle angle in the sagittal plane decreased by $0.71^{\circ}$ (p<0.05). In result, it is confirmed that the functional foot orthotics have a significant effect on mechanical movement of ankle joint for flat foot. it is expected that this paper will be further studied and improved as a practical estimation method in the research on the effect of foot-orthotics.

The surface energy and the effect of functional groups on the surface of the ozone-treated low-density polyethylene (LDPE) film were studied. Treatment conditions were treatment time, total amount of transferred ozone, and ozone concentration. The introduction of polar groups on the surface of LDPE film after ozone treatment was confirmed by FTIR-ATR and XPS analyses. Surface fee energy of the LDPE film was examined by a contact angle method. The ozone treated-LDPE film showed a decreased water contact angles about 15$^{\circ}$ mainly due to the increased concentration of oxygen-containing functional groups, which was attributed to the increased surface free energy or $O_{IS}/C_{IS}$Also, the concentrations of the oxygen-containing functional groups on the surface of LDPE film increased with ozone treatment time and concentration, whereas no significant effects were found for the total amount of transferred ozone. From the dyeability test using Kubelka-Munk equation, it was found that the ozone treatment plays an important role in the growth of oxygen-containing functional groups of LDPE film, resulting in the improvement of dyeability for basic dyeing agent.

Objectives : Posttraumatic stress disorder(PTSD) has been primarily associated with emotional problems. Recently, however, the impact of PTSD on cognitive processes has interested a growing number of researchers. The current study is aimed at investigating the cognitive aspects of PTSD at both behavioral and neurological levels. Methods : We recruited individuals with PTSD who survived the Daegu subway explosion in 2003 as well as non-PTSD individuals as a control group. To evaluate the inhibitory processes and the neural mechanisms, we had these individuals perform the negative priming task simultaneously with functional MRI scanning. Results : Behaviorally, the negative priming effect was intact in the control group but was not evident in the PTSD group. In the imaging results, only the PTSD group showed the negative priming effect (i.e., increased activation of the negative priming condition as opposed to the neutral condition) in the dorsolateral prefrontal cortex, anterior cingulate cortex, and inferior temporal gyrus. The PTSD group also showed increased activity for the positive priming condition as opposed to the neutral condition in the claustrum. These results confirm and extend the previous findings that the integrity of the ACC is compromised in the trauma survivors due to disrupted white matter tract. Conclusions : The current results suggest that deteriorated performance of the PTSD group may be due to the functional problem as well as the structural abnormalities.

Studies on the flavour characteristics of meat-based broth, quantification of flavour-related and functional compounds, and factors affecting the availability of such compounds are minimal. The present study was designed to determine the effects of sex on flavor-related and functional compounds in freeze-dried broth (FDB) made from Korean native chickens (KNC). Male and female KNC from a commercial strain (Woorimatdag$^{TM}$) were reared under similar commercial conditions. FDB was separately prepared using male and female birds aged 100 d (six birds of each sex) and analyzed for nucleotide, free amino acid, betaine, carnitine, carnosine, anserine, and creatine contents, and fatty acid composition. The levels of betaine, carnitine and creatine in FDB were not significantly different between the two sexes (p>0.05) in KNC. Carnosine and anserine were not detected in FDB samples. However, FDB from female chickens had significantly higher inosine-5-monophosphate and arachidonic acid contents than did FDB from male chickens. FDB prepared with male KNC contained higher levels of inosine, linoleic acid, glycine, alanine, lysine, and serine (p<0.05). However, glutamic acid, oleic acid, and DHA were present in comparable amounts (p>0.05) in FDB made from male and female KNC. Our findings suggest that the sex of KNC has significant effect on the contents of flavor-related compounds, but not functional compounds.

The goal of this study was to investigate the effects of a newly developed functional food containing Bacillus polyfermenticus (BP) and other physiologically active materials on the antioxidant system and the process of colon carcinogenesis in male F344 rats. Following a one-week adaptation period, the rats were divided into 3 groups and fed either a high-fat, low-fiber diet (control and DMH groups), or a high-fat, low-fiber diet supplemented with B. polyfermenticus ($3.1{\times}10^8\;CFU/day$) and other physiologically active materials (chitosan, chicory, ${\alpha}$-tocopherol, and flavonoids) (DMH+BP group). One week after the initiation of the diets, 2 groups of rats were subjected to six weeks of treatment with 1,2-dimethylhydrazine (DMH, 180 mg/kg BW, s.c.). The dietary treatments remained consistent throughout the entire experimental period. Nine weeks after the initial DMH injection, the rats supplemented with B. polyfermenticus had significantly lower numbers of aberrant crypt foci than those in the DMH group. Injections with DMH resulted in significantly higher leukocytic DNA damage and plasma lipid peroxidation levels, as well as in a lower plasma total antioxidant potential. These effects were reversed following supplementation with B. polyfermenticus and other physiological materials. Our results indicate that a functional food containing B. polyfermenticus exerts a protective effect on the antioxidant system and on the process of colon carcinogenesis, thereby suppressing the development of preneoplastic lesions.
