The cold surges over East Asia can be grouped to two types of the wave-train and the blocking. Recently, the observational study proposed new dynamical index to objectively identify cold surge types. In this study, the dynamical index is applied to the simulations of 10 climate models, which participate in the Coupled Model Intercomparison Project Phase 5 (CMIP5). Focusing on assessment of cold surge simulation, we discuss characteristic of the wave-train and blocking cold surges in the climate models. The wave-train index (WI) and the blocking index (BI) based on potential temperature anomalies at dynamical tropopause over the subarctic region, the northeast China, and the western North Pacific enable us to classify cold surges in the climate models into two types. The climate models well simulate the occurrence mechanism of the wave-train cold surges with vertical structure related to growing baroclinic wave. However, while the wave-train in the observation propagates in west-east direction across the Eurasia Continent, most of the models simulate the southeastward propagation of the wave-train originated from the Kara Sea. For the blocking cold surges, the general features in the climate models well follow those in the observation to show the dipole pattern of a barotropic high-latitude blocking and a baroclinic coastal trough, leading to the Arctic cold surges with the strong northerly wind originated from the Arctic Sea. In both of the observation and climate models, the blocking cold surges tend to be more intense and last longer compared to the wave-train type.

This paper proposes length rate measurement for relative efficiency that is a core of data envelopment analysis(DEA). It has been said that the linear programming(LP) is a unique method to get the relative efficiency. This method has drawback that applies fractional LP focusing on each DMU in turn. This paper draws bi-dimensional input-output relational graph and distinguishes between efficient and inefficient DMU. The relative efficiency of inefficient DUM is solve using length rate measurement. As a result of various experimental data, the LP shows mistake of application, but this method gets the correct relative efficiency at all times. Also, this method only gets the relative efficiency for only inefficient DMUs without efficient DUMs that already achieved 100% efficiency. This method solves the relative efficiency of inefficient DUM draws the line to efficient frontier and decides the reference set easily.

This study analyzed 10,352 married women to find the correlation between marital equality felt by married women and additional childbirth intentions. Frequency analysis and chi-square test analysis were performed to analyze the general characteristics of the investigator, and studies were conducted through binary logistic regression analysis and interaction analysis to analyze the relevance between each variable and additional childbirth. As a result, the 4-point group based on the 0-point group that lowest marital equality had 2.01 times higher willingness to additional birth. And, the 3-point group and the 2-point group were 1.46 times and 1.41 times higher than 0-point group with marital equality and additional childbirth intentions. In addition, intention of additional childbirth was increased when the higher the number of children, if they own a house, and if wives are non-regular or unemployed. This study analyzed the relationship between married women's intention to give birth additionally, focusing on marital equality. It is suggested that specific and reasonable policies at the macro level are required to improve the fertility rate.

Purpose: We intended to observe relation between general symptom and the number of uterine myoma. Methods: We surveyed 948 women from 35 to 45 years old who had received Korean oriental medical questionnaires about general symptom pattern and pelvic ultrasonography at Kyung-Hee university medical center from May, 2007 to October, 2008. After we divided women into three groups (Mono-uterine myoma, Bi-uterine myoma & uterine myoma above 3) by ultrasonography result, we compared general symptom pattern according to the number of uterine myoma. For statistics, we used Kruskal-Wallis Test, SPSS 13.0 for windows. Results: In relation to sleep pattern, severity of dreaming & awaking showed statistical significance according to the number of uterine myoma. In relation to digestion pattern, appetite & heartburn showed statistical significance according to the number of uterine myoma. In relation to evacuation pattern, hardening of stool showed statistical significance according to the number of uterine myoma. In relation to sweating pattern, severity of refreshing after sweating showed statistical significance according to the number of uterine myoma. In relation to the other patterns, hypertonicity of nape neck showed statistical significance according to the number of uterine myoma(p<0.05). Conclusion: The result showed that prevalence of uterine myoma had to be considered in respect of sleep, digestion, evacuation and sweating pattern. we need further study based on this preliminary result.

The Korean construction industry has led the miraculous economic boost of Korea by providing solid domestic infrastructures such as highway, roads, and airports. It also played a critical role in global construction market and eaned more than 500 billions dollars in terms of their accumulated international orders. However, domestic construction market has significantly decreased in recent years due to the domestic political environments and global economic crisis. Therefore, the importance of international construction market cannot be more emphasized to the Korean construction market in order for the sustainable growth. There has been, however, little research in the area of identifying required competency elements for the Korean construction industry to stay successful in the global market. The main purpose of this study is to identify elements of core competency to increase global competitiveness for Korean construction industry. Core global construction competency elements were derived from the internal and external environmental analyses along with the extensive literature review, expert interviews and a survey. This study utilized the Importance-Performance Analysis (IPA) and a gap analysis in providing insights on the status competitiveness of the Korean construction industry in terms of required global core competency elements. The analysis shows that project management and financial management are the main areas for improvements required to engineering contractors while construction contractors need to take a more balanced approach among technical, project management, and financial management in order to increase their global competencies.

Objectives: This study was conducted to investigate the snack intake and brushing behavior according to the oral health education experience in some schools in Busan, and to investigate whether the oral health education experience affects the snack intake and brushing behavior. Methods: This study surveyed the entire fourth grade of elementary school in two districts by participating in university-linked oral health education activities run under the jurisdiction of the education office business to examine changes in the behavior of elementary school students in their snack intake and toothbrush. The survey was conducted on oral health education in elementary schools, prior oral health education experience before and after the activity, whether or not the brushing classroom was operated, and contents related to eating snacks and brushing behaviors. Result: Among the general characteristics of some schools in Busan, 69.9% of students have experience in oral health education and 30.1% of people have no experience in oral health education. 20.0%, 16.3% were 'normal' and 63.7% were 'helpful'. The brushing behavior according to the oral health education was 44.9% in the number of brushings, 44.9% in the number of brushings, 45.7% in 2-3 minutes in the time of brushing, 41.2% in the brushing method by sweeping the brush up and down. In the daily brushing period, 'after breakfast' was the highest at 72.3%, and the parent's brushing instruction was 'to lead' at 65.1%. The amount of sugar in subjective snacks was the highest with 60.6% of sugar content, and the parents had the highest level of 52.2% for parents' snack intake. This result was more significant than the students without oral health education experience. Conclusion: Based on the results of this study, the number and time of brushing, the method and timing of brushing according to the experience of oral health education. Students who had oral health education experience higher than those who did not have oral health education, but had a lower tendency to brush after lunch at school and before going to bed. For better oral health, the effect of oral health education will be better if the school has more systematic toothbrushing at lunch time and parental guidance at home.

Focusing on khotan located in the southern Silk Route which was one of the most important kingdoms in the Tarim Basin this study attempts to examine the changes of costume in Khotan by compar-ing the costumes in the painted panel showing the story of silk princess with the excavated costumes from ancient tombs. Furthermore this study attempts to inves-tigate the impacts of cultural exchange be-tween China and its western neighboring country Eastern and Western Turkestan on costume. Excavated costumes from the Shanpula ancient tomb in the region of Khotan and from ancient Niya in the esat-ern border of Khotan and discoveries from Rawak and Dandan-oilik near by Yotkan the ancient capital of Khotan are exam-ined. Basic Khotan's costume was the two piece style of tops and trousers. Over the basic costume wearing a top wear with half sleeves was popular. Skirt was worn by women. Even though there were many kinds tops were classified into the two types kaftan and tunic. Thouth Khotan maintained a association with China for a long time the style of Khotan costume had imbued to China. Top wear with half sleeves was worn frequently in Khotan. Also in China top wear with half sleeves was worn as over-wear which was called ban-xiu ban-bi bei-zi Costume style of China is covering the body profoundly and wrapping front edge toward the right. The types of chi-nese top wear with half sleeves for exam-ple round-neck·confronting front edge crossing-neck·confronting front edge tu-nic type discord with the traditional chi-nese costume style There were many cas-es that half sleeved top wear was worn as over wear in T'ang dynasty. The phenom-enon was due to the prevalence of 'ho' (foreign) and half sleeved top wear was introduced by the countries to the west of China Khotan. A round neck garment was a general type for the men of cuntries to the westof China. Also Chinese wore round neck garment since South and North Dynasty The type of Chinese round neck garment was not tunic but kaftan. From costume relics and ancient paintings the type of Khotan's round neck garment was tunic which was recorded on the Chinese histori-cal documents as " guan-tou-shan" that is tunic the type of persian costume, Even thgough the painted panel showing the sto-ry of silk princess was made in the it me when Turks was a dominion on Central Asia Khotan's costume style was not changed toward Turk's costume style and remained tunic style.

This study investigated whether artists' education level, college of graduation, and gender have any influences on artists' premium which leads to higher sales possibility and art price using Art Fair Market data. We found that artists' education level do not have statistically significant effects on either sales possibility or art price. But, artists' college of graduation which was measured by artists' undergraduate school level(high or low) has significant effects on both sales possibility and art price. Artists' gender also has a significant effect on art price, although it does not have any significant effect on sales possibility. These results imply that artists' educational level or degree does not exert significant impacts on artists' premium, while the level of college that artists attended indeed has a significant effect on artists' premium. They also imply that gender plays a role in Korean art market.

This paper studies the characteristics of the restructuring of chemical industrial complex in JiLin city since 1978 focusing on enterprise organization, the process of production, labor, and consumer market. The number of chemical industrial enterprises and their partnership with subcontractors have increased since 2001. As for the type of cooperation group, research institutes and local government are accounted for the greatest portion. The chemical industrial enterprise in JiLin which has adopted Fordism production method still has the highest percentage in 2007. And in the shift process of production system after China's entry into WTO(in 2001), chemical industrial enterprise in JiLin city takes allowing more investment in production technologies as core strategy, while taking improvement in equipment and development of new products as core strategy in the shift process of production technology. The degree of labor re-education was highest in 2007, and as for the relationship between labor and management, enterprises which evaluate the ability of performance of duty are increasing. The characteristics of restructuring of chemical industrial complex on consumer market, domestic market accounted for the greatest portion, on the other side the export is feeble. As for strategy of market restructuring, industrial enterprise in JiLin city should use Quality improvement and high-value added as core strategies to cope with alteration of market.
