Inspiring or mimicking biological bodies is regarded as one of a breakthrough in the conventional engineering. The bird's motion is one of the mimicking objects. Seagulls fly under strong storm at sea. An attempt of investigating into the characteristics of a seagull model's motion and its flow fields has been made in this study. Three cameras, two for motion capture and one for flow field, were used. The motions of the seagull's wing have been reconstructed, and the flow characteristics around the wing have been investigated with 2D-PIV measurements.

This study was carried out to understand and analyze the cooking and processing methods presented in CHE MIN YO SUL (chapter 82~86). The result from the study are as follows; 1. Byung was made from dough of wheat flour, glutinous rice flour, small green peas flour an rice of millet etc. by steaming, roasting, deep fat frying or sauted, or it had eaten Byung which was made from egg or seagull's egg without cereal was simillar to Korea's fried egg cake. 2. Jong and Youl were steamed product made from mixture of millet and rice which were wrapped with leaf of Julpool or bamboo's leaf. It's shape was simillar to Korea's Song-Pyun but different from materials and cooking method. 3. Jamyong's cooking method was boild the mixture of white rice soup, Myong-Jup, and salt. and then pour the rised Bal. 4. Ye and Lo were boiling product made from new oat and appricot seed flour. It was simillar to sweet drink made from rice, and put them in the jar for storage.

This paper is focused on splitting of the first Soviet theatre, MKhAT and collapse of Soviet theatre. A close attention has been paid to Art Theatres's circumstances leading to splitting, critical conscience about division between ideal and real theatres and other concrete situation before the verge of collapse. Administrative reform of the Soviet theatre at the period of Perestroika and Glasnost', its results and conflicts, occurred in the process of transition into market system. These are considered under the premise of that the problems of MKhAT were not so different to the other soviet theatres at that time. As it is known that Moscow Art Theatre is a symbol of Russian theatre. And the status of MKhAT as a symbol of Russian theatre had formulated not only the well-known Stanislavsky' system and his legendary performance The Seagull, Three Sisters etc. It was made by party's effort to make MKhAT as the first Soviet theatre and by directors, artists and critics, they had believed and tried to protect idea of MKhAT as the 'battlements' of Soviet theatrical art. One of them is O. Yefremov, a former leader and artistic director from 1970 to 2000. Actually from the periods of Sovremennik Yefremov knew that does not exist the ideal MKhAT, excepting myths, legends and administrative attitudes. Nonetheless he chose the duty of MKhAT's artistic director to construct ideal MKhAT, theatre as the best moral institution, theatre as union based on common belief. It is same motive that he had led split of MKhAT. But split of theatre did not bring the expected results. After spliting MKhAT has become almost collapsed under collapse of USSR and subsequent turmoil at 1990's. And as soviet theatre disappeared into history, Russian theatre became lost its special significance, the super-theatre's idea.

In this study, a real-sized experimental equipment (pilot plant) was built at the site based on the preliminary research data to develop a movable separator for the mixed construction waste that can be implemented in agricultural areas to review its feasibility through the evaluation of its separation efficiency by waste types. The final construction of the movable separator and experimental results of the separation efficiency are summarized as follows. 1) The separation performance according to the blade type was the best for the combustible wastes either with 26 numbers of L-type blades and 32 numbers of pin type blades. As far as combination of blade types, when the L-type and pin-type were combined, the best separation efficiency was achieved. 2) The separation efficiency for waste wood by the conveyor type and angle of inclination (slope) of the trommel was the best when the conveyor had ribs of seagull shape with the angle of inclination 45°. 3) The separation efficiencies by process showed that 65.9% was separated as inorganic demolition wastes, 18.2% as waste woods, and 16.0% as combustible wastes at conveyor speed of 2-3 rpm, and the error rate was the least from the waste types generated in the dismantle site.

The Boziguoer A-type granitoids in Baicheng County, Xinjiang, belong to the northern margin of the Tarim platform as well as the neighboring EW-oriented alkaline intrusive rocks. The rocks comprise an aegirine or arfvedsonite quartz alkali feldspar syenite, an aegirine or arfvedsonite alkali feldspar granite, and a biotite alkali feldspar syenite. The major rock-forming minerals are albite, K-feldspar, quartz, arfvedsonite, aegirine, and siderophyllite. The accessory minerals are mainly zircon, pyrochlore, thorite, fluorite, monazite, bastnaesite, xenotime, and astrophyllite. The chemical composition of the alkaline granitoids show that $SiO_2$ varies from 64.55% to 72.29% with a mean value of 67.32%, $Na_2O+K_2O$ is high (9.85~11.87%) with a mean of 11.14%, $K_2O$ is 2.39%~5.47% (mean = 4.73%), the $K_2O/Na_2O$ ratios are 0.31~0.96, $Al_2O_3$ ranges from 12.58% to 15.44%, and total $FeO^T$ is between 2.35% and 5.65%. CaO, MgO, MnO, and $TiO_2$ are low. The REE content is high and the total ${\sum}REE$ is $(263{\sim}1219){\times}10^{-6}$ (mean = $776{\times}10^{-6}$), showing LREE enrichment HREE depletion with strong negative Eu anomalies. In addition, the chondrite-normalized REE patterns of the alkaline granitoids belong to the "seagull" pattern of the right-type. The Zr content is $(113{\sim}1246){\times}10^{-6}$ (mean = $594{\times}10^{-6}$), Zr+Nb+Ce+Y is between $(478{\sim}2203){\times}10^{-6}$ with a mean of $1362{\times}10^{-6}$. Furthermore, the alkaline granitoids have high HFSE (Ga, Nb, Ta, Zr, and Hf) content and low LILE (Ba, K, and Sr) content. The Nb/Ta ratio varies from 7.23 to 32.59 (mean = 16.59) and the Zr/Hf ratio is 16.69~58.04 (mean = 36.80). The zircons are depleted in LREE and enriched in HREE. The chondrite-normalized REE patterns of the zircons are of the "seagull" pattern of the left-inclined type with strong negative Eu anomaly and without a Ce anomaly. The Boziguoer A-type granitoids share similar features with A1-type granites. The average temperature of the granitic magma was estimated at $832{\sim}839^{\circ}C$. The Boziguoer A-type granitoids show crust-mantle mixing and may have formed in an anorogenic intraplate tectonic setting under high-temperature, anhydrous, and low oxygen fugacity conditions.

Sexual dimorphism in birds refers to male-female differences in body size, plumage, color and/or behavior. In general, many seabirds, including the family of Laridae, are monomorphic in plumage-color, which makes the determination of sex difficult in the field because both parents also tend to share a great portion of parental care. The development of an inexpensive sexing tool facilitates understanding the degree of sex-specific parental care in the evolution of the life history. Here, we developed a non-invasive method for the determination of sex using the bill-head morphometric of known captive pairs and applied this tool to wild pairs to document factors underlying male-female parental care during the incubation period of Saunders's gulls (Saundersilarus saundersi). Males exhibited relatively larger bill-head ratios than their mates within naturally formed pairs in captivity, resulting in the determination of sex in12 wild pairs at the nest during the incubation period. Males and females equally shared the incubation role during the daytime, attending the nest at a high rate of 95%. However, the male's proportion of nest attentiveness greatly increased with time towards sunset, presumably reflecting the male duty for nighttime incubation. The present study provides a non-invasive method for the determination of sex in a monomorphic seagull species and highlights how male-female incubation behavior is associated with time of the day, rather than other ecological conditions.
