Objectives : This clinical research was conducted to test Patients with Tinea Pedis by using functional soap Gaia 1400, containing medicinal herbs Methods : Total 24 patients who visited Oriental Medical Ophthalmology & Otolaryngology & Dermatology of Dongguk Ilsan Hospital from June 17th, 2008 to November 11th, 2008. They used functional soap daily during 8 weeks. We Observed change of erythema, scaling, vesicle, pustule, exudate, crust and pruritus after 4weeks and 8 weeks. Also Clinical evaluation I, II were used to evaluate the effects of Gaia 1400. Results : 1. There were no significant differences on sex, age and onset. 2. Statistically. After treatment(4,8weekes) Tinea Pedis symptoms score showed significant effect on Tinea Pedis. And the score of using Gala 1400 after 8 weeks is lower than 4 weeks. 3. After 8weeks of treatment, Gaia 1400 showed meaningful effect on Clinical global evaluation I, II. 4. Tinea Pedis Exacerbated in a case after using Gaia 1400 and in the 4 cases Skin dryness Incerased. Conclusion : Considering the above results, we can speculate that functional soap Gaia 1400, containing medicinal herb has some therapeutical effects in mitigating the symptoms of Tenia Pedis.

Recent events in the nuclear industry have resulted in a movement towards increased seismic and LOCA excitations and requirements that challenge current fuel designs. AREVA NP's GAIA fuel design introduces unique and robust characteristics to resist the effects of seismic and LOCA excitations. For demanding seismic and LOCA scenarios, fuel assembly spacer grids can undergo plastic deformations. These plastic deformations must not prohibit the complete insertion of the control rod assemblies and the cooling of the fuel rods after the accident. The specific structure of the GAIA spacer grid produces a unique and stable compressive deformation mode which maintains the regular array of the fuel rods and guide tubes. The stability of the spacer grid allows it to absorb a significant amount of energy without a loss of load-carrying capacity. The GAIA-specific grid behavior is in contrast to the typical spacer grid, which is characterized by a buckling instability. The increased mechanical robustness of the GAIA spacer grid is advantageous in meeting the increased seismic and LOCA loadings and the associated safety requirements. The unique GAIA spacer grid behavior will be incorporated into AREVA NP's licensed methodologies to take full benefit of the increased mechanical robustness.

The purpose of this study was to get a possibility of maintenance architecture, which present instead of contemporary architecture through interrelation between Organic architecture and Gaia theory. Through this study to fine a interrelation part between Organic architecture and Gaia Theory as general case, and through the Gaia theory, Organic architecture being progress as new design experiment exposition. After modern time, we can have presentation of main subject which corresponds to mechanical rationalism and rising Organic architecture from Organic Holism. Organic architecture is get close to biological or ecological access to nature and environment so from and inner order could apply to architecture after that better circumstances and maintenance(sustain architecture) development could possible, although the point became more importance. In this point, Jim E. Lovelock's Gagia theory which try to proscript relationship(element of enviroment) of earth, this is pretty big deal and we can find a connection with Organic architecture in the theory.

Like Hipparcos, Gaia is designed to give absolute parallaxes, independent of any astrophysical reference system. And indeed, Gaia's internal zero-point error for parallaxes is likely to be smaller than any individual parallax error. Nevertheless, due in part to mechanical issues of unknown origin, there are many astrophysical questions for which the parallax zero-point error ${\sigma}({\pi}_0)$ will be the fundamentally limiting constraint. These include the distance to the Large Magellanic Cloud and the Galactic Center. We show that by using the photometric parallax estimates for RR Lyrae stars (RRL) within 8kpc, via the ultra-precise infrared period-luminosity relation, one can independently determine a hyper-precise value for ${\pi}_0$. Despite their paucity relative to bright quasars, we show that RRL are competitive due to their order-of-magnitude improved parallax precision for each individual object relative to bright quasars. We show that this method is mathematically robust and well-approximated by analytic formulae over a wide range of relevant distances.

Recently, inertial sensors like gyros and accelerometers have been quite miniaturized by Micro Electro-Mechanical Systems (MEMS) technology. JAXA is developing a MEM-based GPS/INS hybrid navigation system named Micro-GAIA. The navigation performance of Micro-GAIA was evaluated through off-line analysis by using flight test data. The estimation errors of the roll, pitch, and azimuth were $0.03^{\circ}$, $0.05^{\circ}$, $0.05^{\circ}$ $(1{\sigma})$, respectively. he horizontal position errors after 60-second GPS outages were reduced to 25 m CEP. The attitude errors and position errors are nearly half of ones reported previously[2]. Furthermore, using the adaptive Kalman filters, the robustness against the uncertainty of the measurement noise was improved. Comparing the innovation-based and residual-based adaptive Kalman filters, it was confirmed that the latter is robuster than the former.

We discovered 722 open clusters within 1 kpc using Gaia DR2 data. These clusters are detected in the proper motion space and confirmed on the spatial distribution with parallax information. We divided the 3628 regions and visually searched using python program. Among 722 open clusters, 430 clusters are previously unknown clusters. Catalogue of discovered clusters is unloaded on the online catalogue at https://radio.kasi.re.kr/project/shlee/. Owing to the good membership criteria, we could see the halo structure of the clusters. In that reason, the average size of the discovered cluster is about 9 times than that of previously known clusters.

The presence of double red clump (RC) in the Milky Way bulge is widely accepted as evidence for a giant X-shaped structure originated from the bar instability. We suggested, however, a drastically different interpretation based on the multiple stellar populations phenomenon as is observed in globular clusters. Our discovery of a significant difference in CN-band between two RCs strengthens our scenario. On the other hand, recent Gaia survey provides trigonometric parallax distances for more than one billion stars in our Galaxy. These distance measurements would provide the important test as to the origin of the double RC in the Milky Way bulge. In this talk, we will present our preliminary results from Gaia DR2.
