This essay, based on an oral presentation, provides the non-specialist, with an evaluation of the Mongols' influence and China and, to a lesser extent, on Russia and the Middle East. Starting in the 1980s, specialists challenged the conventional wisdom about the Mongol Empire's almost entirely destructive influence on global history. They asserted that Mongols promoted vital economic, social, and cultural exchanges among civilizations. Chinggis Khan, Khubilai Khan, and other rulers supported trade, adopted policies of toleration toward foreign religions, and served as patrons of the arts, architecture, and the theater. Eurasian history starts with the Mongols. Exhibitions at the Metropolitan Museum of Art and the Los Angeles County Museum of Art confirmed that the Mongol era witnessed extraordinary developments in painting, ceramics, manuscript illustration, and textiles. To be sure, specialists did not ignore the destruction and killings that the Mongols engendered. This reevaluation has prompted both sophisticated analyses of the Mongols' legacy in Eurasian history. The Ming dynasty, the Mongols' successor in China, adopted some of the principles of Mongol military organization and tactics and were exposed to Tibetan Buddhism and Persian astronomy and medicine. The Mongols introduced agricultural techniques, porcelain, and artistic motifs to the Middle East, and supported the writing of histories. They also promoted Sufism in the Islamic world and influenced Russian government, trade, and art, among other impacts. Europeans became aware, via Marco Polo who traveled through the Mongols' domains, of Asian products, as well as technological, scientific, and philosophical innovations in the East and were motivated to find sea routes to South and East Asia.

Full-scale measurements of wind action on the open roof structure of the WuXi grand theater, which is composed of eight large-span free-form leaf-shaped space trusses with the largest span of 76.79 m, were conducted during the passage of Typhoons HaiKui and SuLi. The wind pressure field data were continuously and simultaneously monitored using a wind pressure monitoring system installed on the roof structure during the typhoons. A detailed analysis of the field data was performed to investigate the characteristics of the fluctuating wind pressure on the open roof, such as the wind pressure spectrum, spatial correlation coefficients, peak wind pressures and non-Gaussian wind pressure characteristics, under typhoon conditions. Three classical methods were used to calculate the peak factors of the wind pressure on the open roof, and the suggested design method and peak factors were given. The non-Gaussianity of the wind pressure was discussed in terms of the third and fourth statistical moments of the measured wind pressure, and the corresponding indication of the non-Gaussianity on the open roof was proposed. The result shows that there were large pulses in the time-histories of the measured wind pressure on Roof A2 in the field. The spatial correlation of the wind pressures on roof A2 between the upper surface and lower surface is very weak. When the skewness is larger than 0.3 and the kurtosis is larger than 3.7, the wind pressure time series on roof A2 can be taken as a non-Gaussian distribution, and the other series can be taken as a Gaussian distribution.

The importance of emotional intelligence education in the development of children's augmented reality education content is overlooked. Therefore, in-depth research is needed to develop children's emotional intelligence. This study was conducted through theoretical consideration and case analysis. The proposal of this paper is that the augmented reality type for children aged 2 to 7 is suitable for indoor activities with marking recognition technology. To promote an understanding of emotions, a large screen is selected, and emoticon dolls or emoticon books are recommended for learning content. Children aged 7 to 11 are suitable for indoor activities of non-marker recognition technology, and can induce emotional control and emotional recognition through active manipulation. For the learning content, "3D art teaching content" and "Online Classic Musical" are recommended. Children after the age of 11 are suitable for non-marker recognition technology outdoor activities and improve each element of emotional intelligence through interaction with nature and society. For the learning content, 'Forest Play Activity through Art' and 'EQ Theater Play' are recommended. Through this paper, we intend to promote the development of children's augmented reality emotional intelligence education.

This study investigates the effect of consumer involvement in the relationship between customer satisfaction and loyalty (which is measured as consumers' repurchase and WOM intentions). Previous research has presented inconsistent implications on the role of consumer involvement in the relationship. Some researchers have presented the empirical results showing that consumer involvement moderates the relationship, whereas others have done the empirical results implying that the consumer involvement does not moderates. In sum, the previous empirical studies have provided the inconsistent empirical results that consumer involvement may be a moderator or a non-moderator in the relationship between customer satisfaction and loyalty. Thus, we start this research with two research questions: "Does consumer involvement has a moderation effect on the relationship between-customer satisfaction and loyalty across various service industries?" and "Can the moderation effect of consumer involvement be detected differently depending on the statistical methods used to probe the moderation effect?" A questionnaire survey was conducted in the context of four service categories: eight service firms for fast food, four firms for family restaurant, four firms for movie theater and four firms for Bakery. Hierarchical regression analyses (moderated regression analyses) and chi-square difference tests were used to identify the role of consumer involvement in the relationship between customer satisfaction and loyalty. The empirical results show that there does not exist the difference in the moderation effects of consumer involvement identified by the two statistical methods (i.e., hierarchical regression analyses vs. chi-square difference tests), however, that there exists the difference in the identified moderation effects of consumer across service categories. In the final section, we summarize the implications and re-interpret the empirical results provided in the previous studies.

In this paper, we proposed the skin color based hand and finger detection technology for the gesture recognition in CCTV surveillance. The aim of this paper is to present the methodology for hand detection and propose the finger detection method. The detected hand and finger can be used to implement the non-contact mouse. This technology can be used to control the home devices such as home-theater and television. Skin color is used to segment the hand region from background and contour is extracted from the segmented hand. Analysis of contour gives us the location of finger tip in the hand. After detecting the location of the fingertip, this system tracks the fingertip by using only R channel alone, and in recognition of hand motions to apply differential image, such as the removal of useless image shows a robust side. We explain about experiment which relates in fingertip tracking and finger gestures recognition, and experiment result shows the accuracy above 96%.

We experienced the seven cases of penetrating and non-penetrating cardiac injuries combined with cardiac tamponade from June 1986 to June 1989 at Seoul and Chun-An Hospital of SOONCHUNHYANG medical college. The results were as follows. l. In sex distribution, 7 cases were male. In age distribution, The fourth decades occupied about 58 % of all cases. 2. In mode of injury, 4 cases were stab wounds, 1 case penetration by metallic fragment, 2 cases blunt chest trauma. 3. We routinely checked the CVP with subclavian vein catheterization in case of suspicious cardiac tamponade. Significant increments were showed in 4 cases. 4. Becks triad [low blood pressure, raised central venous pressure, distant heart sound] were recorded in 43 % of the cases with proven tamponades. 5. The sites of injury included RV in 4 cases, LV in 1 case, RA in 1 case and branch of RCA in 1 case. The RV injuries were the most common. 6. Coronary artery damage occurred in 2 cases. LADA was severed in 1 case combined with RV rupture and branch of RCA was torn 1 case. 7. Pericardiocentesis was performed 1 case at another hospital before referring to our hospital. We have never used the procedure because we think that it is potentially dangerous with no clear benefit. 8. Subxyphoid pericardial window was performed in 2 cases of severe cardiac tamponade. We have employed this method to stabilize the patients who had systolic hypotension. 9. Surgical approaches were performed with median sternotomy in 3 cases, thoracotomy in 4 cases. 10. We undertook the simple closure in 6 penetrating cardiac wounds. The removal of impacted metallic fragment was performed under the cardiopulmonary bypass. Simple ligation was performed in 2 cases of coronary artery severance 11. One patient with no sign of life was urgently intubated and undertaken an emergency room thoracotomy on the stretch car without antiseptic preparation. The cardiorrhaphy in 6 cases were performed in the operating theater 12. One patient undertaken emergency room thoracotomy did not survive due to refractory hypovolemic shock. But the remaining 6 patients recovered.

Mt. Nam (265m), a city park of Seoul, was originally covered with a typical deciduous broad-leaved forests in Central Korea. However, the park forests have been changed the development for various purpose such as the construction of castle wall, road way, broadcasting station, theater, hotel and apartments, in addition, to thoughtless plantation or alien plant introduction. Human population growth from ca. 100 thousands persons less in that time established Seoul as the capital of choseon dynasty in 1394 to ten millions over persons at present, accelerated the vegetational changes of the park. mt. Nam boundary in those days of sunjong (1908) also was much shrinked as much the range of 300 m distance in the northern most to 700 or 800m distance in some places. The actual vegetation of Mt. Nam largely can be classified by floristic composition into two plant communities of Quercus mongolica community and Pinus densiflora community, four plantations of Pinus rigida, Robinia pseudo-acacia, Populus tomentiglandulosa and other tree species, and on mixed forest with native and alien tree species in secondary succession stage (Yim et al. 1987). The restoration movement of Mt. Nam toward to the natural condition of forest or biodiversity is moving now. However, in the movement there are some problems such as the lack of ecological consideration and the undesirable decision of priority in the practice. A warning should be given, especially, on the undesirable plantation of non-native tree species restricting the forest succession, as in the case of southern slope of Mt. Nam. First of all, the most importance in Mt. Nam management is that the restoration for natural forest and biodiversity should be carried on the basis of integrated ecological principles based on the site evaluation.

There are some problems in inhalation sedation of non-cooperative pediatric patients. Usually the pediatric patients reject the nasal hood and there's no cooperation for administration of nitrous oxide gas. In mouth breathing patient, other technics of sedation such as intravenous or oral sedation or general anesthesia were recommended. Common causes of mouth breathing are common cold, allergic rhinitis, sinus problem, anatomical disorder, and habitual mouth-breathing. However in some patient not indicated the general anesthesia and high failure rate in oral and intravenous sedation. Administration of $N_2O-O_2$ with suction catheter was applied in full mouth breathing patient. Clinically effective sedation were occurred during procedure about 45 to 55 minutes. There's no any side effects by $N_2O-O_2$ inhalation sedation. The patients awoke at the end of the procedure and received 100% oxygen for 2-3 minutes. There's still some problems in use of the suction catheter such as air pollution of operation theater and elevate arterial carbon dioxide tension.

In this study, the method to generate facial animation of SVG format based online character AUtomatically was proposed. The re-targeted character can reproduce the modeling facial movements itself without losing the unique formative properties by modeling abundant facial movements of the character in the existing animation for movie theater through the mathematical calculation and 'retargeting' this to other character of SVG format. The method of retargeting facial movements like this can be applied to the various characters by only one facial data so although non-specialists, even not an animator can create facial animation of character easily and rapidly. The suggested facial movement in this study is nonlinear and an exaggerated motion so it is friendly to the viewers and it is lively. Besides, it is based on the SVG format, so the smooth facial movements can be implemented by less capacity than existing GIF animation.
