This paper proposes a new guidance law, which considers the Field of View (FOV) of the seeker when a missile has a strapdown seeker mounted instead of a gimbal seeker. When a strapdown seeker, which has a narrow FOV, is used for tracking a target, the FOV of the seeker is an important consideration for guidance performance metrics such as miss distance. We propose a new guidance law called hybrid guidance (HG) to address the shortcomings of conventional guidance laws such as proportional navigation guidance (PNG), which cannot maintain lock-on conditions against high speed targets due to the narrow FOV of the strapdown seeker. The aim of the HG law is to null miss distance and to maintain the look angle within the FOV of the strapdown seeker. In order to achieve this goal, we combine two guidance laws in the HG law. One is a PNG law to null the LOS rate, and the other is a sliding mode guidance (SMG) law derived to keep the look angle within the FOV by employing a Lyapunov-like function with a sliding mode control methodology. We also propose a method to switch these two guidance laws at certain look angles for better guidance performance.

The aim of this research is to propose the final shirt design modified for new senior women that fulfills their emotional and physical needs. The modifications were based on the results of in-depth interviews and literature search, and the study was conducted in order to understand the desires and preferences of senior women, as consumption of outdoor-wear by the group continues to increase. To develop the design of outdoor-wear that satisfies the physical and emotional qualities and preference of the new senior women, six different designs with lines, combined materials, as well as materials that were layered, pleated and draped were proposed using virtual-dressing simulation software. Then, the modified designs were derived from the six original designs by reflecting the opinions collected in the in-depth interviews with eleven women in their 50s. The responses in the interviewed showed a preference for lines, pleats and layers, as these features made the clothes look trendy, gave it a slender-look, and improved the body shape of the women. As the color is the critical factor for outdoor-wear, there was an overwhelming preference for primary colors by the women, which was in contrast to their color preference in general clothes. A sleeve design modification was proposed to convert the half-sleeves to 3/4-long sleeves in order to account for changes in body temperature at menopause, and to satisfy the aesthetic needs for covering wrinkles. Research of new senior outdoor-wear designs will help segment and differentiate strategies for the increasingly fierce competing outdoor market, as well as l provide directions in the design creation process using the simulation of 3D virtual model.

In the original mixtures of experts framework, the parameters of the network are determined by gradient descent, which is naturally slow. In [2], the Expectation-Maximization(EM) algorithm is used instead, to obtain the network parameters, resulting in substantially reduced training times. This paper presents the new EM algorithm for prediction. We show that an Efficient training algorithm may be derived for the HME network. To verify the utility of the algorithm we look at specific examples in time series prediction. The application of the new EM algorithm to time series prediction has been quiet successful.

In this paper Author introduce a new field named Artificial Life and its main directions of research. That is the research of evolutionary robot and artificial brain. Then author explored the advanced scientific thought hidden in them. Furthermore, the author tries intuitively to show a new type of control that is heuristically raised from artificial life research. It could be named as evolutionary control. This type of control is more like human body´s structure, and it is self-organized.

The materialism prevalent in the modern industrial society and concern for the destruction of nature have led people to long for the returning to nature and excite their nostalgia for old. These phenomena induced in modern fashion naturalism retrospectivism ethnicism and primitivism. In the following we present our findings in regard the roles and relationships of the tie dying with the modern fashion design. in regard the roles and relationships of the tie dying with the modern fashion design. The common basic themes are founded as follows; 1. Naturalism: The tie dying is from very old times and has evolved in many parts of the world producing their own natural designs and color. They bear the characteristic of nature; the pleasantness smoothness and complexity. 2. Individualism and hand made: No two items produced by the tie dying technique are identical even though they are similar by design and their individuality is to some extent determined by chance. The retrospetivism and individualism are themes relating to the modern fashion. 3. Ethnicism and primitivism: The tie dying brings up the 'ethnic and traditional' to us and their designs and colors present the new images of the ethnic and primitive influences to the modern designs. 4. Ecology recyle and grunge look: The tie dying represent the recycle of the used natural resources such as making the old cloths useful again in new forms by tie dying them. The old clothes thus restored show wrinkled untidy and somewhat loosely fit form. This image of 'grunge look' is one of the central theme of the modern fashion.

The purpose of this study is for affirmation about fashion and film industry has very important relationship through the image of film fashion in 1990. To this processing , films in 1990 were analyzed by the back ground, time place, persons's status are expressed in period movie but the person's characters, development of story mood in contemporary movies. The contents of this study are as follows : First, film fashion which was related mass fashion design and concept development and fashion designers as constume services were considered. Second, the change of star image through the 20th century. The roles and new image of film fashion in period movies and contemporary movies in 1990 were searched. Third, proposal and results were confirmed for expansion of fashion industry and film industry together. Finally, from the latter of 20th century, a lot of fashion designers have participated in film works than before, So the images of films were sued and reflected as new mass trend . Especially retro-romantic mood was expressed in fashion trend due to period movie fashion. Also minimal city look and elegance glamourous look are represented cause of contemporary movie fashion. Therefore, the cooperation between film productions and fashion professionals is very important for promotion of Korean culture development in 21st century, 'the century of image'.

This paper describes two algorithms for technology mapping of multiple output functions into interesting and popular FPGAs (Field Programmable Gate Arrays) that lise look-up table memories. For improvement of technology mapping for FPGA, we use the functional decomposition method for multiple output functions. Two algorithms are proposed. The one is the Roth-Karp algorithm extended for multiple output functions. The other is the novel and efficient algorithm which looks for common decomposition functions through the decomposition procedure. The cost function is used to minimize the number of CLBs and nets and to improve performance of the network. Finally we compare our new algorithm with previous logic design technique. Experimental results show significant reduction in the number of CLBs and nets.

The purpose of this study is to analyze the formative characteristics and the aesthetic values of the Military style in the 20th century and the images of the Military look shown in recent collections. The results of this study are as follows; 1) The aesthetic values of the Military style includes authority, functionality, resistibility and bisexuality. Authority is represented in suits and coats attaching details such as epaulets, flap pockets, gold buttons and badges. Functionality is represented in pants suits and skirts suits which are comfortable and simple. Resistibility is represented in wrinkled, dirty-old and torn military items. Bisexuality is shown on the military pants suits that a skirt or a mink coat is draped over. 2) The Military look in collections are expressed in classic, romantic, sexual, sporty, avant-garde and ethnic images. Classic images are appeared in suits and coats attaching details such as epaulets, flap pockets, gold buttons and badges. Romantic images are represented in the military items made of pastel-tone lace or splendid colored silk. Sexual images are appeared in designs to expose or to focus in women's body. Sporty images are represented in the military items made of new materials such as cotton-fleece, cotton-jersey and tencel. They have camouflage prints, melange-gray and fluorescent colors. Avant-garde images are appeared in the deformed suits and outer made of special materials with camouflage prints, khaki, gray and black. Ethnic images are represented in wearing military and ethnic items at the same time or military items made of ethnic colors, prints and handmade details.
