  • Observations have indicated that magnetic reconnect ion may occur frequently in the photosphere and chromosphere as well as in the solar corona. The observed features include cancelling magnetic features seen in photospheric magnetograms, and different kinds of small-scale activities such as UV explosive events and EUV jets. By integrating the observed parameters of these features with the Sweet-Parker reconnect ion theory, an attempt is made to clarify the nature of chromospheric magnetic reconnection. Our results suggest that magnetic reconnect ion may be occurring at many different levels of the photosphere and chromosphere without a preferred height and at a faster speed than is predicted by the Sweet-Parker reconnect ion model using the classical value of electric conductivity. Introducing an anomalous magnetic diffusivity 10-100 times the classical value is one of the possible ways of explaining the fast reconnect ion as inferred from observations.

  • A high performance liquid chromatographic method was developed for the simultaneous determination of free and glycine conjugated bile acids. Free and glycine conjugated bile acids were extracted from bear gall bladder by methanol and from serum using a Sep-pak $C_{18}$ catridge. The extracted bile acids were labeled with 2-bromoacetyltriphenylene in acetonitrite using 18-crown-6-ether as a catalyst. Derivatized bile acids were separated from the individual bile acids on a reversedphase column (Chemcosorb 5-ODS-H) using acetonitrile-methanol-water(10:50:30) as a mobile phase and monitored by an UV-detector at 254nm. Linearities of calibration curve were obtained between 4 ng and 24 ng, and recoveries from bear gall bladder sample were higher than 94%.

  • H${\alpha}$ transient bright kernels may be an important diagnostic of energy conversion processes occurring in the choromosphere during flares. We observed an H${\alpha}$ kernel that occurred in AR 11263 in associated with a small flare on 2011 Autust 5th using the Fast Imaging Solar Spectrograph installed at the 1.6m New Solar Telescope of Big Bear Solar Observatory. We find that both the H${\alpha}$ line and the CaII 8542${\AA}$ line appear in emission, with a red asymmetry in that they display red wings of enhanced emission. The red asymmetry shows 5-30 km/s downward motion for 8 minutes. We determine some physical parameters by adopting the Cloud mode and discuss the physical meaning of these results.

  • Backgroun and purpose: The purpose of this study was to find out the effect of high heel shoes on lumbar lordosis for young ladies. The most of ladies wear high heel shoes at least 4 to 5 days a week. Subjects: Subjects were 30 young ladies age between 20 to 30 years old who go to the Sahm Yook University. Methods: Participants were static standing position with bear feet, tennis shoes. and 6cm high heel shoes each different time. The ankles of subjects were 15 degree plantar flexion with 6cm high heel shoes. Metrecom Skeletal Analysis System v. 3. 10 was used to measure the lordosis of each subject. Results: The angle of the lordosis with high heel shoes showed the significant decrease omparing with the angle of lordosis with bear feet and tennis shoes. The mean difference is 2.57 degree. Conclusion: There is strong relationship between the high of heel with decreasing the lumbar lordosis(p<0.05).

  • We have examined the relationship between the speeds of coronal mass ejections (CMEs) and the GOES X-ray peak fluxes of associated flares. Noting that previous studies were possibly affected by projection effects and random association effects, we have considered two sets of carefully selected CME-flare events: four homologous events and four well-observed limb events. In the respective samples, good correlations are found between the CME speeds and the GOES X-ray peak fluxes of the associated flares. A similarly good correlation is found for all eight events of both samples when the CME speeds of the homologous events are corrected for projection effect. Our results suggest that a close relationship possibly exists between CME kinematics and flaring processes.

  • In this study the characteristics of Korean furs and peltry were discussed in the terms of usage and kinds from the literature survey of the relevant references, The following con-clusions were deduced. From Ancient to Koryo a kind of acient of Korea a lot of furs and peltry were produced and dressed. The leopad of Gochosun Korea was worthy of gold as an expensive goods to China. red dyed pelt of Silla Korea was traded with China and that pelt dyeing tech-nology of that pelt developed. The marten of Koryo was trade to Arabia and an otter skin to Kum Dynasty as loved goods. Korean furs and peltry made a reputation and were used for trading goods with China Japan and Arabia. Tratment technology in Korea became known to foreign country. There is another record that sheep and camels were offered to Koryo by around countries, And that Koryo employed men of Kum Dynasty as a shepherd. From ancient to Koryo Korea had had many kinds of furs of peltry as using goods such as leopard mart otter skin panther bear, manchurian wapili, fox, porpoise rat, mankey, horse, pig, wild bear, goat, cow, cat, dog, tiger, deer, raccoon dog and so on.

  • Human desire is required to be changed variously as time flows. A theme park which is planned to male a good memory including a variety of story, drama, and experience with one of themes is increasingly and currently broaden to be a good economic value of cultural tourism for the local autonomy institution or individual business. The plan for a theme park should be developed to give the tourist satisfaction at studious and ecology educational needs in conformity with our country's distinctive four seasons, its surrounding environment, facilities, and its contents. This design which is called 'Bear theme park' has only one theme focused on a combined effort with a landscape designer and a sculptor. It is estimated that the park must be our country's unique model of a theme park The purpose of this study is to request the designer's direct construction to participate in it by themselves, to solve any problems on the design side, to experience the real construction procedure, and to take the designer's techniques, and skills as soon as the design completed.
