Painting is well regarded as a stratified structure by the conservators and restorers. Hence, the scientific methods have been developed for the study of the interal layer of paintings. Examples of such methods are X-ray, infra-red, and ultra-violet photography. A more direct method is to look at the painting in cross section under the microscope and to analyze pigments using an electron probe X-ray micro analyzer(EPMA).In this research, I study and analyze twenty two Korean paintings of self-portraits including the first oil painting of Hui Dong Koh's self-portrait stored in the museum of Tokyo National University of Fine Arts and Music, employing these scientific techniques. The small fragments taken from the ground layers of the early oil paintings(1915∼1942)are analyzed using the EPMA. According to their main materials, the ground layers can be classified into five types ; 1. Lead white layer and double layer of calcium carbonate and lead white, 2. Zinc white with some mixiture of lead white, 3.Titanium white with some barium white, 4. Barium white, 5.Double layer of titanium white and zinc white.

This paper presents a phase portrait analysis-based safety control algorithm for excavators, using adaptive sliding mode control. Since working postures and material types cause the excavator's rotational inertia to vary, the rotational inertia was estimated, and this estimation was used to design an adaptive sliding mode controller for collision avoidance of the excavator. In order to estimate the rotational inertia, the recursive least-squares estimation with multiple forgetting was applied with the information of the swing velocity of the excavator. For realistic evaluation, an actual working scenario-based performance evaluation was conducted. Based on the estimated rotational inertia and an analysis of estimation errors, sliding mode control inputs were computed. The actual working scenario-based performance evaluation of the designed safety algorithm was conducted, and the results showed that the developed safety control algorithm can efficiently avoid a collision with an object in consideration of rotational inertia variations.

The purpose of this study is to examine symbolic meanings of costumes shown by portraits of King Henry VIII and use them as basic data for research on costume design of historical dramas in the Renaissance or on King Henry VIII's costume. This study attempted analysis of symbolic meanings from the paintings-related various domestic and overseas literatures, preliminary study paper, and web sites etc. The symbolic meanings expressed by the portraits of King Henry VIII are characterized by authority, innovation performance, authority, masculinity, innovation performance, artistic taste, intellectual charm, intrepidity and benevolence. Especially, the portraits of King Henry VIII symbolized his masculine beauty by emphasizing sexual attractiveness that cannot be seen in portraits of other kings through broad shoulders and exaggerated codpiece which are the zenith of masculine beauty during the Renaissance age. Through the image of King Henry VIII which was painted with jester or barber surgeons, his characteristic and open mind thinking highly of the technique and human life was also expressed. In the portrait of King Henry VIII, various images set in knights' tournament, playing a musical instrument and reading a book as well as the image of wearing a parliament costume were shown, highlighting King Henry VIII as a person good at both literary and martial arts with open and innovative personality than any other kings in history.

During 50 years, the chaotic theory has begun to research with concerning in Mathematics and physics, and it has extended the fields to of engineering and social science. Recently, chaotic theory has progressed as a type of fusion research fused with natural science and social science. Such fused research includes problems for addiction, happiness of human, problem happened between family and love affairs between man and woman. In this paper, we consider the external environment based on love model which is one among fusion research, and when we consider colored noise in the external environment, we verify how the chaotic pattern is affected in the love model through time series and phase portrait.

This study is on the reproduction of King Sejong's costume presented in at the National Classical Music Institute in the late of 2008. The performance was presented focusing on the idea of ceremonial music of hoi-ryeyeon produced in the reign of king(1433). The reproduction of King Sejong's costume was undertaken to keep pace with the times and to pay due regard to the performance costume. The implications of the study are as follows. King Sejong's Hoi-ryeyeon ceremonial costume is a royal robe(gonryongpo), the best one of king's clothing. The basic type of gonryongpo is that of fastening four yongbos to danryoung. The type of gonryongpo is, therefore, made with reference to unearthed articles and portrait of the first king of the Yi dynasty. The yongbo is larger one than the late period of the Yi dynasty in the light of portrait of the first king of the Yi dynasty. The supporting type of gonryongpo is that of gonryongpo, dapho, and chulrik, king's dress granted by Myeong dynasty. In the late period jikryeong was used as supporting dress and fixed to be lining and included jikryeong. Therefore the order of supporting dress was jikryeong, dapho and chulrik and was reproduced with reference to unearthed articles in the early Yi dynasty, as did the small piece of crown, belt and shoes.

We say that human have an animal of emotion. There are various kind in the emotion of human. One of among them, love has been studied in sociology and psychology as a matter of great concern. In this paper, we propose a novel love model with the delay time as response time for love. We also consider it in the Romeo and Juliet of love model to analyze their romantic behaviors. First we consider the Juliet only have a time delay, Romeo only have a time delay, and both Romeo and Juliet have a time delay. We represent their behaviors as time series and phase portrait, and we analyze their difference.

Jose Donoso's Casa de campo is an uncertain and ambiguous novel because it has a political allegory on one hand and metafiction on the other. The novel may well be considered a political allegory about the 1973 military coup in Chile. This understanding, however, oversimplifies the fictional world of Casa de campo. In the deep level of the narrative, the novel is a literary portrait of challenges and failures that occurred in Latin American history. As metafiction, Casa de campo features discourses on the literary portrait and calls attention to reality outside the novel. Therefore, Donoso seeks to reveal the unusual, temporary and fictional character of the grim reality.

The purpose of this study is to develop measurement program model for a human being-oriented product through the between the evaluation factors of portrait and general preferences of portraits. We added new items that are essential to the image evaluation by analysing previous studies. In this study, We identified the facial focus for the first step, and the portraits were evaluated by dividing it into objective and subjective image quality evaluation items. RSC Contrast and Dynamic Range were selected as the Objective evaluation items, and the numerical values of each image could be evaluation items, and the numerical values of each image could be evaluated by statistical analysis method. Facial Exposure, Composition, Position, Ratio, Out of focus, and Emotions and Color tone of image were selected as the Subjective evaluation items. In addition, a new face recognition algorithm is applied to judge the emotions, the manufacturer can get the information that they can analyze the people's emotion. The program developed to quantitatively and qualitatively compiles the evaluation items when evaluating portraits. The program that I developed through this study can be used an analysis program that produce the data for developing the evaluation model of the product more suitable to general users of imaging systems.
