Objectives : There are lots of reports that cardiovascular disease, including hypertension, cerebro-vascular accident, and coronary heart disease, is related to atherosclerotic changes. Increased serum levels of lipids could play a role in these changes. This study aimed to investigate the relationship between PWV and risk factors of cardiovascular disease, including serum lipid values. Methods : This study included 261 subjects ($49.32{\pm}11.79$ years, 112 male) who underwent PWV and serum lipid evaluation. We investigated the correlation between serum lipid values, blood pressure, body mass index (EMI) and PWV. Pearson's correlation and partial correlation analysis were applied to examine the relationship between PWV and risk factors of cardiovascular disease. Results : Serum triglyceride, total cholesterol, systolic blood pressure, and diastolic blood pressure were significantly correlated with PWV. Partial correlation coefficient adjusted by age yielded significant correlation between serum triglyceride, systolic blood pressure, diastolic blood pressure and PWV. Conclusion : In this study, it seems that there are significant relationships between PWV, triglyceride and blood pressure. We could suggest that PWV might have some relationships with Dam-eum and blood stasis in oriental theory.

This study is the spatial characteristics of child education facilities through the cognitive development of child. Early childhood is the most important period in every human developmental stage; physical, emotional, and mental parts. Thus, the education in early childhood should be conducted naturally by a variety of experiences, sensibility, and physical activities, not by knowledge-oriented education which has been conducted until today. The education based on experience has been adapted, not only domestically, but internationally, and the early childhood education focused on child's development is especially emphasized in Europe. It's because the industrialization started earlier in Europe than in other countries, and it leaded to the entry of women in public affair. Consequently, early childhood education was taken charge of by the nation. While it has gone through trial and error, and Now it leaded to the better way. This study checks the common factors which shows the spatial characteristics based on experience and the relationship between the features of infants and concept of space in Piaget's theory. And then, I am going to systemize the relationship of each factor and suggest the design plan so that it could be applied methodologically when the space is designed for child education facilities beyond the current education only focused on programs.

This study investigates the history of economics for answering how the discipline originating from a sub-discipline of moral philosophy ended up being an amoral science. I show that economic theory, at its first stage of development, has retained a place in which morality could play a role within liberalist framework, but has removed the very place as it developed into its current image. I argue that it is the Walrasian paradigm that completed this amoralizing process in economics. One theoretical assumption of complete contract in the Walrasian paradigm, creates the institutional environment where economic agents are free from any moral consideration. I show that if the assumption is relaxed, the problem of economic agents' morality should reappear in the stage. Accepting the assumption of incomplete contract opens a way to restore the room for economic agents' moral considerations in economic discourses. Finally I breifly survey the recent discussions on the role of sympathy in economics.

From several commercialized games the technique of changing facial expressions is imported, and a design method of a game character for the player's empathy is expected to be diversified in the future. In this paper, as a design method of a game character for the player's empathy, this makes walking motion for the game character applied with 'human-emotion' factors as statistics variation of a game character in RPG genre. After this paper implements analyzed emotions of human facial expression and walking motions applied with emotion in examples of character animation theory, this paper divides walking motion applied with human-emotion factors into 8 types through relationship to statistics factors in RPG genre. And then these are applied to a knight character, which has the most similarity with human's physical feature of the game characters in RPG genre, and makes walking motion as variable statistics. As a game player controls the game character applied with 'human-emotion' factors, the effect of the player's empathy about the game character becomes higher, and the level of immersion in game play is also expected to increase.

At present, the time of easy oil and gas is over. Now, the largest part of fossil fuels is concentrated in the deepest levels of tectonic structures and in the sea shelves. One of the most cumbersome operations of their extraction is the bore-hole drilling. In connection with austere tectonic and climate conditions, their drivage every so often is associated with great and diversified technological difficulties causing emergencies on frequent occasions. As a rule, they are linked with drill string accidents. A key role in prediction of these situations should play methods of theoretical modelling. For this reason, there is a growing need for development and implementation of new numerical methods for computer simulation of critical and post-critical behavior of drill strings (DSs). In this paper, the processes of non-linear deforming of a DS in cylindrical cavity of a deep bore-hole are considered. On the basis of the theory of curvilinear flexible rods, non-linear constitutive differential equations are deduced. The effects of the longitudinal non-uniform preloading, action of torque and interaction between the DS and the bore-hole surface are taken into account. Owing to the use of curvilinear coordinates in the constraining cylindrical surface and a specially chosen concomitant reference frame, it became possible to separate the desired variables and to reduce the total order of the equation system. To solve it, the method of continuation the solution by parameter and the transfer matrix technique are applied. As a result of the completed numerical analysis, the critical states of the DS loading in the cylindrical channels of inclined bore-holes are found. It is shown that the modes of the post-critical deforming of the DS are associated with its irregular spiral curving prevailing in the zone of bottom-hole-assembly. The possibility of invariant state generation during post-critical deforming is established, condition of its bifurcation is formulated. It is shown that infinite variety of loads can correspond to one geometrical configuration of the DS. They differ each from other by contact force functions.

The purpose of this study is to propose divergence from standardization of animation acting through working on investigating gestures comprising most principal exaggeration acting elements in animation acting. For this purpose, this study utilizes animation 12 principles and Laban's effort theory. This study respectively analyzes 2D and 3D animation gesture expressions that are standards for comedy silent film and derive commonness and difference from them. In the next, this study explores the possibility of how animation can utilize acting of comedy silent film. Charles Chaplin and Buster Keaton used to be important elements referring to early animation acting, but as the recent animation technology gets advanced, they are not treated significantly any more. However, as 3D animation turns out to be chief concerns and the roles that acting, dynamics and performance play become gradually important, the necessity is on the rise that Charles Chaplin and Buster Keaton's gesture performances should more prudently be reinterpreted.

Given a set S of n points in the plane, a minimum-diameter spanning tree(MDST) for the set might have a degree up to n-1. This might cause the degradation of the network performance because the node with high degree should handle much more requests than others relatively. Thus it is important to construct a spanning tree network with small degree and diameter. This paper presents an algorithm to construct a spanning tree for S satisfying the following four conditions: (1) the degree is controled as an input, (2) the tree diameter is no more than constant times the diameter of MDST, (3) the tree is monotone (even if arbitrary point is fixed as a root of the tree) in the sense that the Euclidean distance from the root to any node on the path to any leaf node is not decreasing, and (4) there are no crossings between edges of the tree. The monotone property will play a role as an aesthetic criterion in visualizing the tree in the plane.

Animation, presenting laughing, tears and inspiration to the audience, can be classified into several genres according to the structure of scenario and storytelling in the same ways as for movie. This classification of scenario genre and scenario writing is based on the writing for a play. Scenario writing and genre classification that were discussed mainly in the movie theory books has been applied to the animation in spite of the difference of the production technique and storylines. Animation finds its academic values as a movie art due to its frame-by-frame filming technique and the diversity in the production. Since the number of scenario writers for animation is much smaller than that of movie in Korea, it is needed to set an academic basis for the classification of genre and scenario writing. In this study, academic basis for the classification of the genre by the analyzing the animation works.

As the Trump administration withdraws the Paris Climate Agreement and shows its antipathy toward free trade, the U.S.'s soft power is most likely to weaken and its behaviors could be perceived as acts to surrender the U.S. hegemonic leadership in the world stage. Hegemonic stability theory notes that the existence of a hegemonic power contributes to international stability in the sense that it provides international public goods. A lack of the U.S's leadership in international politics, however, could be recognized as its denial of a hegemonic status. Is it intentional or accidental? The U.S's denial of hegemonic roles is the byproduct of the Trump administration's "American First" policy, not the showcase of its intention to transit hegemony to others. What is noteworthy is that China targets a niche market of hegemony as the U.S. denies its roles as the international leader. Put it another way, China attempts to ride hegemony for free when the U.S. denies its hegemonic roles accidentally. Faced with a niche market of hegemony, China has begun to accelerate its national strategy to make "Chinese Dream" come true. To that end, China promised again to keep the Paris Climate Agreement and attempts to play more active its roles in Shanghai Cooperation Organization(SCO), Asia Infra Investment Bank(AIIB), and "One Belt, One Road". Despite all these efforts, the U.S. is most likely to withdraw its denial of hegemony any time soon. The U.S's resumption of Freedom of Navigation Operations(FONOPs) could be a precursor of the return to a hegemonic power's willingness. In this vein, it is noteworthy that the South China Sea serves as a quasi-war zone for hegemonic conflict.

Plant industry is one of technology-intensive and most prosperous industries in Korea because of its recent prosperity and promising outlook in export. However, no Korean EPC company has yet been well prepared in lifting their capacity sufficient enough to get the upstream conceptual or basic design and engineering orders for sizable plant projects which are known as the more value-added. If systems engineering, a methodology which developed complex systems such as airplanes and has been justified its effectiveness in Defense and NASA projects, can be integrated with plant engineering which should be developed and applied based on the requirements of so many stakeholders, conditions, lifecycle concepts, and constraints of the projects, huge synergic effect is expected particularly in developing a specific upstream design, which is a conceptual or basic design. The notion of integration with each other between systems engineering and plant engineering can be really the crux of EPC's success in any plant projects. This paper suggests an approach showing a methodology how to dig out, analyze, evaluate, verify and implement the stakeholders' requirements into a plant design in conceptual phase using the theory and skills of systems engineering. ISO/IEC 15288 well known systems engineering standards is used. Carbon capture system is used for a case study, for it is an emerging technology in reducing emissions of carbon dioxide causing global warming from flue gas after combustion. Here systems engineering was proven to play a substantial role in enhancing the capability of designers in developing a conceptual design of whole plant or certain part of crucial plant systems.
