Lady Han, Gongshin-buin(恭愼夫人韓氏: 1410~1483) was Gongnyeo of Ming emperor and sister of Han Hwak(韓確:1400~1456). The aim of this study is to analyze the characteristic of costume presents for Lady Han, and to investigate a part of Joseon women's attire in the 15th century. Most of the presents for Lady Han were native products of Joseon to help alleviate her homsickness, but surviving relics are very rare. The costume-related presents included daily accessories and fabrics such as natural ornaments, embroidered pouch, needle case, wig, wooden comb, portable knife with multi-blades, various colored plain silk [綿紬] and ramie. Also, preceding research analysis of costume relic were combined with study of presents for Lady Han's. The most salient costume of Joseon women in the 15th century was the symmetric collared jacket. In addition, ornamented jeogori, pouch with pine nut stitch, chima, jangot, jangsam, black veil[羅兀] made with ra or jeung, glass beads, paintings of Ming and Joseon can be references. Illustrations show 6 representative type of Joseon women's full attires in the 15th century are as follows. First, is a combination of 'symmetric collared jacket with peacock rank badge, jeoksam, chima, underwear' and 'hoa-a, janga-a, embroidered pouch, needle case, knife with multi-blades: presents for Lady Han'. Second, formal wear focusing on symmetric collared Jacket of cloud pattern. Third, formal wear focusing on multicolor ornamented jeogori. Fourth, town wear with jangot and neoul. Fifth, formal wear with jangsam. Sixth, daily wear focusing on banbi with symmetric squre collar. Accessories and underwear shown in another illustration were same as the first illustration. Results of this study can be used as content for making historically accutate costumes as well as costume education.

This paper presents a traffic control agent that can perform the dynamic resource allocation by controlling traffic flows on a DiffServ network. In addition, this paper presents a router that can support DiffServ on Linux to support selective QoS in IP network environment. To implement a method for selective traffic transmission based on priority on a DiffServ router, this paper changes the queuing discipline in Linux, and presents the traffic control agent so that it can efficiently control routers, efficiently allocates network resources according to service requests, and relocate resources in response to state changes of the network.

This paper presents a framework for processing a structured approach of R&D investment. It presents nine steps to operate R&D investment from analysis of environment situation to review and feedback its activity. Also fundamental questions fur effective R&D management in business are discussed and after that critical eight success factors for R&D investment are discussed.

This paper presents an analytical framework of Conceptual Understandings of Earth Systems (CUES) that shows a relationship between disciplinary knowledge of Earth systems and the specific thinking skills required to understand that knowledge. This framework is developed through an extensive literature review of students' and teachers' understandings of earth systems concepts and systems thinking in earth science context. This study first presents the categories of disciplinary knowledge of Earth systems, Earth System Knowledge (ESK). This study then illustrates a relationship between categories of ESK and the ontological categories (Matter, Process, Systems) that has been used to study students' conceptual understandings of Earth systems. Finally, this study presents the CUES framework to show the relationship between disciplinary knowledge and thinking skills. The implications of using this framework for curriculum development, assessment, and teacher education and ESS research are discussed.

This paper presents a systematic approach for estimating material performance of concrete mixture design based on satisfaction curves developed from statistical evaluation of existing or newly obtained material property related data. In performance based material design (PBMD) method, concrete material used for construction of a structure is designed considering a structure's specified performance requirements based on its usage and characteristics such as environmental conditions, structure types, expected design life, etc.Satisfaction curves express the probabilities that one component of substrates (i.e., aggregate size, cement content, etc) of concrete mixture will sustain different criterion value for a given concrete mixture design. This study presents a statistical analysis method for setting up concrete material parameter versus concrete criterion relationships in the form of satisfaction curves and for estimating confidence bounds on these satisfaction curves. This paper also presents an analysis method to combine multiple satisfaction curves to form one unique satisfaction curve that can relate the performance of concrete to a single evaluating value. Based on several evaluated mixture design examples for various material properties, the validity of the proposed method is discussed in detail.

This paper describes a point matching method that is based on an expansion of the electromagnetic field in terms of a series of Bessel and modified Bessel functions multiplied by trigonometric functions. In this method, the electric and magnetic fields inside the waveguide core are matched to those outside the core at matching points on the boundary to yield matrix equations. As an example applying this method, the paper presents the results of the computation in the form of curves of the propagation constants in a semicircular optical waveguide, be formed by annealing for reduced insertion(radiation) loss when connected to optical fiber. The propagation curves are presented in a form of refractive index independent. Also, it presents relative energy distributions between inside the core and outside the core of various modes and presents field distributions.

At its simplest, this essay provides a narrative of migration in Asia since the arrival of Homo sapiens some 70,000 years ago. More fully, it presents the case for conducting long-term, world-historical interpretation for Asia with attention to multiple perspectives, which has become increasingly central to global historical analysis. Following an introductory articulation of the benefits of long-term interpretation, the second section presents a balance of three perspectives-empire, exchange, and migration-as frameworks for interpreting the Asian past. The third section presents further detail on migration in long-term Asian history. The concluding section identifies four changes in patterns of migration during the past two centuries and emphasizes the underlying importance of cross-community migration in long-term human biological and social evolution.

The most concerning issue in these days is the energy crisis by increasing threat of global warming and depletion of natural resources. In the situations, the Plug-in Hybrid Electric Vehicle (PHEV) is drawing attention from many countries for the next generation's car which has higher fuel efficiency and lower environmental impact. This paper presents simulation results about the limit capacity of central power-grid which doesn't have enough surplus electric power for charging PHEVs. Therefore, this paper also presents a smart charging system that can charge the PHEVs with a function of distributing demands of charging. The smart charging system is an agent facility between the government and consumer, which can recommend the best time to charge the battery of PHEVs by the lowest energy cost. This function of choosing time-slots is the technical system for the government which wants to control the consumption rate of electric power for PHEVs. Finally, this paper presents the economic feasibility of PHEVs from the two kinds of price system, midnight electric price and home electric price.

To analyse the royal marriage of Yi-Dynasty, the authors studied 'Kuk Hon Geong Rea', which is a historical record, published in 1749(King Yong-Jo), on the usage of marriage articles in the royal family. The essential steps or articles described in the record were as follows, Royal marriage of King : Wedding presents, black and red silks from the bridegroom's to bride's, proclamation of Queen and wedding ceremony(納采) (納徵) (冊妃) (親迎 尊雁 同牢). Royal marriage of Crown Prince : Wedding presents, black and red silks from the bridegroom's to bride's. proclamation of Crown Princess, wedding ceremony, and bride's gifts to her parents-in-law(納采) (納徵) (冊嬪) (親迎 尊雁 同牢) (朝見體). Royal marriage of Crown Princess : Wedding presents, black and red silks from the bridegroom's to bride's, wedding ceremony, bride's gifts to her parents-in-law(納采) (納徵) (尊雁 同牢) (見舅姑禮). Necessary articles for weddings were different according to royal status of the member in the royal family.
