This study is purposed to analyse the effects of long-term & one-time 10km running exercise from bone metabolic marker change on bone metabolism. 7 male members(18.6±1.08) from a marathon club were subjected to the study. They were allowed to do long-term 10 km running training once a week for 6 months. And bone metabolism mark was determined according to the respective times : before/after 6 months training, before/after 10 km race, one day after the race, 3 days after the race. The examination items of bone metabolism mark were serum calcium, phosphorus, paratyroid hormone, osteocalcin, calcitonin, alkaline phosphatase in blood and calcium, phosphorus, deoxypyridinolin in urine. The results of study were as follows; 1) There was no change in deoxypyridinolin and alkaline phosphatase but there was significant change in calcitonin, paratyroid hormone and osteocalcin(p<.01). 2) There was no change of Calcium in serum and urine but there was significant change of phosphorus in blood(p<.01). To make a conclusion, it is determined that long-term 10 km running at low intensity and low frequency tends to restrict bone metabolism circulation, but exercise at a little high level activates bone metabolism into building up bones and absorbing bones and finally shows up high bone metabolism circulation, which is inferred to have an effective influence on bone health. It is considered there is a possibility that different exercise intensity, even same kind of exercise, influences on bone metabolism sdifferently.

Actinomycetes were isolated from soil to find new antibiotics. An active antimicrobial compound was isolated from the culture filtrate of Actinomycetes AF 21-3. The Actinomycetes strain which showed strong antifungal activity against Candida tropicalis and Microsporum gypseum was identified as Streptomyces fimbriatus and named as Streptomyces fimbriatus AF 21-3.

The incidence of coexisting hyperparathyroidism and empty sella syndrome is rare and the etiology and incidence of their coexistence is not known. The association of hyperparathyroidism and the empty sella syndrome may be related to multiple endocrine neoplasia (MEN) syndrome due to a genetic disorder. We experienced a rare case of hyperparathyroidism presenting as acute pancreatitis combined with empty sella. We report here a 37-year old female who manifested epigastric pain because of acute pancreatitis. She had hypercalcemia due to parathyroid adenoma. A pituitary gland was not visible in the sella turcica on MRI scans. On genetic analysis, she did not show a mutation of the MENIN gene. Empty sella is thought to be a coincidental finding with hyperparathyroidism.

Most previous robots had used the wheels as means for movement. These structures were relatively simple and easy to control and this is why the method had been used until currently. However, there are many realistic problems to move from one place to another in human life, for instance, steps and edges. So we need to develop the two-legged walking humanoid robot. The 2-legged walking Robot system has been vigorously developed in so many corporations and academic circles of several countries. However, 2-legged walking Robot has been mostly studied in view of the static walk. We design a stable humanoid Robot which can walk in high-speed through the research of the dynamic walk in this paper. Especially, worldwide companies have been interested in developing humanoid robots for a long time to solve the before mentioned problems so that they can become more familiar with the human form. The most important thing, for the novel two-legged walk, is to create a stable and fast walking in two-legged robots. For realization of this movement, an optimal mechanical design of 12 DOFS, a distributed control and a parallel processing control are implemented in this paper. This paper proves that high speed and stable walking can be achieved, through experiments.

The film with methylcellulose(MC) and grape seed extract(GSE) were prepared by casting their aqueous solution at 80℃ and drying at 23℃ for 48 hrs. Effect of grape seed extract(GSE) on the barrier permeabilities and the thermomechanical property of methylcellulose(MC) film was studied. The barrier permeabilities and the thermomechanical property of MC film containing various contents of GSE were evaluated in terms of water vapor, oxygen permeabilities, and dynamic mechanical analysis(DMA). The rate of water vapor permeability of MC film decreased with GSE contnets in the MC films. Also, the rate of oxygen permeability also decreased with GSE contents indicating higher oxygen barrier property of MC film. The results showed that GSE had a good miscibility with MC and acted as a plasticizer for MC film resuling in lowering the glass transition temperature of the film.

The characteristics of ichthyofauna and fish community in the Lagoon Gyeongpo, Korea were investigated from May to October 2005. The total number of fish caught during the period was representing 26 specis and 18 families. Most dominant species was T. hakonensis(50.65%) and subdominant specis was A. flavimaus(25.41%). K. punctatatus(11.07%), M. cephalus(6.53%), E. japonicus(1.46%), C. castaneus(1.01%) were also numerous. The total biomass of collected fish showed 147.00kg, 135.83kg, 85.60kg,23.76kg, repectively. A pattern of the fish community according to seasonal veriations appear to be related tp spawning periods of species. Comparison of the ichthyofauna in present study with the references from early years suggests that there has been a gradual decrease, in composition, of primary freshwater specis accompanying with the increase of peripheral freshwater and seawater specis.
