Main objectives of this study were to increase digestibilities of indigestible ingredients in spent mushroom composts (SMC) consisted of sawdust mainly as well as to fortify conversion of inorganic Se present in SMC to organic Se via fermentable microbial actions. Experimental feeds were designed to contain the increasing level of selenium (0.06ppm, 0.54ppm, 1.26ppm and 1.86ppm) in combination with SMCs of Se-enriched and non-Se mushrooms. Feeds were also fermented using commercial microbial feed additives (Sambae, Ltd., Korea) comprised Saccharomyces, Bacillus, Aspergillus, Streptococcus and Actinomycetes before feeding trial for Hanwoo (Korean native cattle). Those were fermented for 0, 12, 24, and 48 hrs. Initial pH was linearly increased as Se concentration increases or the proportion of SMC of Se-enriched mushroom increased (p<0.0001). pH values of fermented feeds (0.54ppm, 1.26ppm and 1.86ppm) containing SMC of Se-enriched mushroom were not different since 12 hrs of fermentation time and their pH was significantly lowered compared to control group. The increasing level of Se concentration in fermented feeds showed significant differences in organic and inorganic Se contents and proportion of organic Se among treatments. As a SMC proportion of Se-enriched mushrooms in the fermented feed was increased, organic Se proportion was significantly decreased (p<0.0001). The control treatment (0.06ppm) comprising the non-Se SMC only was estimated of the organic Se to be 100% and the treatment groups containing the increasing level of Se were estimated of organic Se to be approximately 70%.

Introduction : A positive thinking has been known to affect the enhancement of performance. One of temperament characters, harm avoidance is thought to be associated with anxiety related behaviors. Golfer showed highest anxiety and lowest score of harm avoidance, compared to any other sports. We hypothesized that positive feedback and reinforcement in golfer would decrease the anxiety and improve the performance. Methods : Fifty one golfers with the age from 15 to 19 were classified into two groups; 25 golfers who used Zinsser's Changing Negative thoughts to Positive thoughts and Beswick's positive self talk when exercise and competition (P-FB) and 26 golfers who had not (controls). Harm avoidance, Spielberg's Trait and State Anxiety, and Golf scores has been assessed at baseline and 6 months later. Results : There was no significant difference in baseline harm avoidance, anxiety, and golf scores between P-FB and controls. The total golf scores in both groups have improved after 6 month later. However, P-FB group showed greater improvement of total scores and putting scores, compared to controls. The state anxiety in PFB group has been decreased, while there was no change in controls. The change in the state anxiety was correlated with harm avoidance and the change in total golf scores. Discussions : The positive thinking has enhanced performance and state anxiety. The improvement of performance and anxiety in golfers was associated with high harm avoidance. The current study showed that the regulation of anxiety with positive thinking was helpful to the performance enhancement in subject with high harm avoidance.

Ginseng was first addressed ever in the medical record in HyangYakGooGupBang (鄕藥救急方), the oldest Korean medical book published in Kingdom of Goryeo (918-1392) when Ganghwa was the provisional capital city at the time. It is believed that ginsengs in Ganghwa were planted and cultivated from 1100s. Intensive ginseng production in Ganghwa began when Ganghwa became the special district of the Kaesong Ginseng Union (開城人蔘組合) in 1920s, this intensive production continued till the Korean War in 1950. After the Korean War ended in 1953, ginseng production was resumed. In 1967, Ganghwa Ginseng Association (江華蔘業組合) was founded. The total acreage of ginseng harvested was nearly 200 ha in 1967 and it increased to ha 900 in 1974. By mid-1970s, Ganghwa became the largest ginseng region in Korea by total production and acreage. Most of ginseng roots cultivated in Ganghwa are six years old. Ganghwa, which was already well-known for red ginseng productions, has become even more famous for ginseng production.

This study was conducted to evaluate the efficacy of human milk fortifier (HMF) on growth and nutritional status in growing rats fed infant formula supplemented with HMF. Three week-old male Sprague-Dawley rats were divided into three groups and fed regular formula (RF), premature formula (PF) and regular formula fortified with HMF (RF+HMF) diets for 3 weeks. There was no significant difference in weight gain among groups. However, a significant increase of food intake was observed in PF and RF+HMF groups compared with RF group. With increasing food intake, the intakes of carbohydrate and protein were significantly increased in PF and RF+HMF groups. The weight of perirenal fat was significantly increased in rats fed RF+HMF; however, the weights of liver, kidney and spleen were not significantly different among groups. Although total lipids, total cholesterol, HDL-cholesterol concentrations of serum were not significantly different among groups, triglyceride was significantly increased in PF group. The triglyceride and total-cholesterol of liver were significantly increased in rats fed regular formula fortified with HMF and PF compared with RF group. Glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT), creatinine (Cre) and blood urea nitrogen (BUN) in serum showed no significant difference among groups. The concentration of growth hormone was significantly increased in PF group compared with other groups. The concentration of hemoglobin was significantly increased in rats fed PF and RF+HMF. These results suggest that the supplementation of human milk fortifier in growing rats may promote growth as increasing food intake and lipid contents in tissues and prevent the anemia of infants.

The purpose of this study is to evaluate the effects of surface treatment and composition of reinforcement material on fracture strength of fiber reinforced composite inlay bridges. The materials used for this study were I-beam, U-beam TESCERA ATL system and ONE STEP(Bisco, IL, USA). Two kinds of surface treatments were used; the silane and the sandblast. The specimens were divided into 11 groups through the composition of reinforcing materials and the surface treatments. On the dentiform, supposing the missing of Maxillary second pre-molar and indirect composite inlay bridge cavities on adjacent first pre-molar disto-occlusal cavity, first molar mesio-occlusal cavity was prepared with conventional high-speed inlay bur. The reinforcing materials were placed on the proximal box space and build up the composite inlay bridge consequently. After the curing, specimen was set on the testing die with ZPC. Flexural force was applied with universal testing machine (EZ-tester; Shimadzu, Japan). at a cross-head speed of 1 mm/min until initial crack occurred. The data was analyzed using one-way ANOVA/Scheffes post-hoc test at 95% significance level. Groups using I-beam showed the highest fracture strengths (p<0.05) and there were no significant differences between each surface treatment (p>0.05) Most of the specimens in groups that used reinforcing material showed delamination. 1. The use of I-beam represented highest fracture strengths (p<0.05) 2. In groups only using silane as a surface treatment showed highest fracture strength, but there were no significant differences between other surface treatments (p>0.05). 3. The reinforcing materials affect the fracture strength and pattern of composites inlay bridge. 4 The holes at the U-beam did not increase the fracture strength of composites inlay bridge.

Purpose: This study aimed to evaluate the influence of surface sealants on the surface roughness of composite resins. Materials and Methods: The study used microfilled composite resin (Metafil CX, Sun Medical Co.) and hybrid composite resin (Aelite^TM LS posterior, Bisco). Sixty specimens (8 mm in diameter and 4 mm in height) of each composite resin type were prepared and divided into 3 groups. Each specimen was ground with 600, 1000, and 2000-grit sandpaper. The Surface roughness (Ra) values were measured using a surface roughness tester (SJ-301, Mytutoyo) before and after surface sealant application. Surface sealants, BisCover^TM LV (Bisco), Optiguard^® (Kerr), and Seal-n-Shine^TM (Pulpdent), were applied to the specimens, as instructed and observed by scanning electron microscope (JSM-7500, JEOL) and atomic force microscope (MultiMode IV, Veeco Instruments). Results: Specimens ground with 600-grit sandpaper coated with surface sealants exhibited significantly lower Ra values than the untreated group (P < 0.05). Specimens ground with 1000 and 2000-grit sandpaper showed statistically no difference. There was no significant difference in surface roughness among BisCover^TM LV, Optiguard^®, and Seal-n-Shine^TM. SEM and AFM revealed remarkably decreased microdefects on the surfaces of composite resins after surface sealant application. Conclusion: Surface sealants can influence surface roughness when applied on the rough surface of composite resins but not on highly polished composite resins.
