For the study of fine-scale structure and dynamics in the solar chromosphere, the Fast Imaging Solar Spectrograph (FISS) was installed in 1.6m New Solar Telescope at Big Bear Solar Observatory in 2010. The instrument, installed at a vertical table of the Coude lab, is properly working and producing data for science. From the analysis of the data, however, we noticed that a couple of problems exist that deteriorate image quality : lower light level and poorer resolution of the CaII band data. After several tests, we found that the relay optics at the right position is crucial role for the spatial resolution of raster-scan images. By using resolution target, we re-aligned relay optics and other components of the spectrograph. Here we present the result of optical test and new data taken by the FISS.

We observed an Ellerman bomb(EB) and its associated surge using the Fast Imaging Solar Spectrograph(FISS) and the broadband TiO filter of the 1.6 meter New Solar Telescope at Big Bear Solar Observatory. As is well-known, the EB appears as a feature that is very bright at the far wings of the H alpha line. The lambdameter method applied to these wings indicates that the EB is blue-shifted up to 6km/s in velocity. In the photospheric level below the EB, we see rapidly growing "granule-like" feature. The transverse velocity of the dark lane at the edge of the "granule" increased with time as reached a peak of 6km/s, at the time of the EB's occurrence. The surge was seen in absorption and varied rapidly both in the H alpha and the Ca II 8542 line. It originated from the Ellerman bomb, and was impulsively accelerated to 20km/s toward us(blueshift). Then the velocity of the surge gradually changed from blueshift of 20km/s to redshift of 40km/s. By adopting the cloud model, we estimated the temperature of the surge material at about 27000K and the non-thermal velocity at about 10km/s. Our results shed light on the conventional idea that an EB results from the magnetic reconnection of an emerging flux tube and pre-existing field line.

Five mimic-animal boxing(五禽戱, FAB) is physical fitness exercises conducted by imitating the motions of tiger, deer, bear, monkey, and bird, devised by the famous doctor Hwa-Ta(華陀) in the Three Kingdoms of China. FAB is one of bionic-physical and breathing exercises(傍生導引) by combined automassage as a practice for health care. Although FAB have effects of health control and medical treatment, but interrelationship of five animals(五禽) of FAB and five viscera(五臟) of five elements(五行) is complicated. So, the present was designed to investigate the progress of FAB, movement-feature of FAB, and the interrelationship of five animals and five viscera. further I will develop value by sports-treatment medicine in oriental medicine. The results were as follows ; FAB is physical exercises of dynamic exercises and new-dynamic exercises. Feature of China-FAB have each movement by imitating the motions of each animals, movements of Formosa-FAB were mixed. In philosophical viewpoint, Five animals (tiger, deer, bear, monkey, bird) were attached to metal, wood, water, earth, fire of five elements, and lung, liver, kidney, spleen, heart of five viscera. In viewpoint of breathing exercises, Five animals (tiger, deer, bear, monkey, bird) were attached to water, wood, earth, fire, metal of five elements, and kidney, liver, spleen, heart, lung of five viscera. Although FAB have effects of health control and medical treatment, FAB have indication and contraindication. Therefore, I think that mechanism of treatment should reason with Oriental medicine doctor in FAB.

This study attempts to analyze the social and cultural meanings of the ethnic groups to which different types of shamans belong in Siberia from the appearance characteristics in terms of clothing through Roland Barthes's semiotic theory. The research method here is to analyze three types of shaman costume classified by Holmberg, which are bird-type, deer-type, and bear-type, through theoretical research and to investigate the analysis process of Roland Barthes's semiotics theory. Roland Barthes's approach to semiotics presents an analysis model that can explore the sociocultural meaning of the Siberian shaman costume. The research results are as follows. In the first type, to be closer to the god of the upperworld, shamans transform themselves into birds by decorating their costumes with the characteristic elements of birds such as feathers and wings. In the second type, the shamans' costumes are made of deerskin, and the headdress is shown in the shape of antlers to make it easier to receive messages from the upperworld and run fast in the underworld. In the third type, the shaman's costume is made of bearskin, the head is covered with bearskin, and the body is decorated with bear pendants. Through the power of the bear, the shaman is sent to the underworld to defeat evil gods and remove diseases. Shamans can show their particularity of being a demigod and non-binary gender through clothing. They use this to reflect their authority as a medium of communication between man and god.

The aim of this study was to analyze the learning curve of a low-volume veterinary surgeon for laparoscopic salpingectomy of Asiatic black bear. A total of 66 Asiatic black bears (Ursus thibetanus) were presented for sterilization using laparoscopic salpingectomy. These 66 bears were divided into three groups of 22 bears according to the order of surgery (A, B, and C groups, 22 bears per group). One veterinarian performed laparoscopic salpingectomy. There was no significant difference in age, body weight, or crown-rump length between groups. The hazard of completion for salpingectomy by 5 minutes was higher (p < 0.0001) in B and C groups than A group, whereas the hazard was not significant different between B and C groups. The factor that affected the hazard of completing salpingectomy by 5 minutes was heart rate, not age or weight. Operation time was 12.61 ± 8.04 minutes for group A, 5.35 ± 4.38 minutes for group B, and 2.80 ± 1.16 minutes for group C. The operation time for salpingectomy shortened over time. However, significant difference in operation time was present only between groups A and C (p = 0.001). The operation time for laparoscopic salpingectomy decreased rapidly for the first 7 bears (p < 0.05). It then decreased gradually until the 66th case. Operation time of laparoscopic salpingectomy was significantly decreased and stabilized after 33 cases (p < 0.05). As a result, the number of bears required for a low-volume veterinary surgeon to be proficient in laparoscopic salpingectomy is 33 or more.

It has been a big mystery what drives filament eruptions and flares. We have studied in detail an X1.8 flare and its associated filament eruption that occurred in NOAA Active Region 9236 on November 24,2000. For this work we have analyzed high temporal (about 1 minute) and spatial (about 1 arcsec) resolution images taken by Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory, Hoc centerline and blue wing ($-0.6{\AA}$) images from Big Bear Solar Observatory, and 1600 ${\AA}$ UV images by the Transition Region and Corona Explorer (TRACE). We have found that there were several transient brightenings seen in H$\alpha$ and, more noticeably in TRACE 1600 ${\AA}$ images around the preflare phase. A closer look at the UV brightenings in 1600 ${\AA}$ images reveals that they took place near one end of the erupting filament, and are a kind of jets supplying mass into the transient loops seen in 1600 ${\AA}$. These brightenings were also associated with canceling magnetic features (CMFs) as seen in the MDI magnetograms. The flux variations of these CMFs suggest that the flux cancellation may have been driven by the emergence of the new flux. For this event, we have estimated the ejection speeds of the filament ranging from 10 to 160 km $s^{-1}$ for the first twenty minutes. It is noted that the initiation of the filament eruption (as defined by the rise speed less than 20 km $s^{-1}$) coincided with the preflare activity characterized by UV brightenings and CMFs. The speed of the associated LASCO CME can be well extrapolated from the observed filament speed and its direction is consistent with those of the disturbed UV loops associated with the preflare activity. Supposing the H$\alpha$/UV transient brightenings and the canceling magnetic features are due to magnetic reconnect ion in the low atmosphere, our results may be strong observational evidence supporting that the initiation of the filament eruption and the preflare phase of the associated flare may be physically related to low-atmosphere magnetic reconnection.
