Unlike former researches, this study for developing the caricature generator began observing the methods that other caricature experts have adopted. According to the observation, it seemed that experts tried to exaggerate characteristics of the target shape from other similar objects. When we are saying "This is similar to that," we give salience to their difference among the identical form groups. This study was to find the most similar geometry form to the target shape and then to transform its form through exaggeration. The research scope was restricted to exaggerate the outline shape of two-dimensional looped curve as a caricature form. For this, the author discussed the following: (a) organization method of four kinds of similar geometry form database, (b) search method to find the pertinent similar geometry form, (c) arrangement method for those searched data, and (d) method to exaggerate the target shape. Human faces and cars were selected as research categories to make the database. According to the survey over the transformed results, it was proved its possibility.

It is an increasing research area to explore mathematics learning from discursive perspectives. However, there have been little studies conducted on why and how discursive perspectives in mathematics learning were adopted and developed. Especially, not much discussion has been done on the later Wittgenstein's philosophical stance in terms of the relationship between language and thought as a background of discursive approach to learning mathematics. This study aims to explore the later Wittgenstein on language to get better understanding about discursive approaches to mathematics learning. For the attainment of this aim, first the later philosophy is compared with the former philosophy in depth. Then the later philosophy is discussed focusing on how his point of view on the world and the language have been changed. After providing an account of his later philosophy, it is clarified that what is discursive approaches to learning mathematics and how this philosophy brace the approaches. This research concludes with implications and limitations, as well as suggestions for future researches.

In this paper. we propose a new autocalibration algorithm. 3D-based image synthesis is roughly divided into two methods. One is using autocalibration method, and the other is using real 3D data like pattern information. The former is more progressive method. because there is no constraint or information about the scenes. Therefore autocalibration method has very difficult progress dealing with complicate non-lineal equations. Nowadays, constraints of camera intrinsic parameters are used in many researches. Therefore we solve the linear equations instead of complicate non-lineal equations. For example, to fix principal point of camera is a representative method.

This paper proposes a framework to construct the synthetic battlefield based aviation engagement simulation model for the distributed system. The proposed framework has the synthetic battlefield in the HLA (High Level Architecture)/RTI (Run-Time Infrastructure) based distributed system to reflect environmental effects into the aviation engagement simulation model. In an aviation engagement, the environment affects weapon systems such as detection and movement. Therefore, environmental effects are required to be reflected in the simulation. However, former researches are inadequate for complex operations of weapon systems that are requirements of the engagement simulation. Thus, the construction of the engagement simulation system of which reflects environmental effects based on environmental data is still difficult. The main objective of this paper is to propose a framework to solve the difficulty and constructs an example system based on the proposed framework.

Mobile computing becomes a new issue of researches in computing due to the advances of mobile equipment and the connection with Internet. In mobile environment, there are many constraints such as limited bandwidth, intermittent disconnection, limited battery life, and so on. By these reasons, broadcasting has been generally used to disseminate data efficiently by the mobile applications. This paper proposes an adaptive broadcasting method which logically divides broadcast channel into the periodic broadcast channel and the on-demand broadcast channel and dynamically assigns the bandwidths of both channel. The former disseminates data that are selected based on both the popularity and the size of each datum, the latter disseminates data that are selected based on the requests of mobile clients. When selecting data to be disseminated, the proposed broadcasting method considers the mobility of a mobile client and also considers the size of each datum by using SF(size factor) proposed in this paper. This paper also evaluates the proposed broadcasting method by measuring the energy expenditure of mobile client in experiments.

In this paper, we propose a method that gives motion command to a mobile robot to recognize human being's hand gesture. Former way of the robot-controlling system with the movement of hand used several kinds of pre-arranged gesture, therefore the ordering motion was unnatural. Also it forced people to study the pre-arranged gesture, making it more inconvenient. To solve this problem, there are many researches going on trying to figure out another way to make the machine to recognize the movement of the hand. In this paper, we used third-dimensional camera to obtain the color and depth data, which can be used to search the human hand and recognize its movement based on it. We used HMM method to make the proposed system to perceive the movement, then the observed data transfers to the robot making it to move at the direction where we want it to be.

This study was analyzed on relationship of blood vessel pressure massage and skin and management method on blood vessel pressure for skin care with Yin-yang 5 factors theory, Yin-yang 5 factors theory of blood vessel pressure massage with related Korean medicine is essential for descriptions of the physiology of human body and disease. Six elements(wind, heat, fire, dryness, wetness, and cold) and seven emotions(anger, happiness, thought, worry, sadness, surprise, and fear) effected on skin care and the five viscera and the six stomach. Blood vessel pressure massage related with skin consists of the five viscera and the six stomach and is improved blood circulation and is retarded aging of skin by controls of hormone and free nerve system. Blood vessel pressure massage for skin care improved in the intestine system and blood circulation and got healthy. The blood vessel pressure massage treatment of beauty art can aid the function of bio-rhythm of a human body and make our body health by healing the problems of the five viscera organs and the six stomach. It also help circulate of the blood flow and vigor. The study expects the related researches to improve the various treatments through this treatment. The researcher encountered many problems with the lack of concerned materials and former studies but expects this study to be a study to retard aging the skin and prevent the diseases through the study of the blood vessel pressure massage.

This research is related to the evaluation of rural amenities. Since the UR negotiations, the wave of market liberalization has brought many difficulties to the rural areas. This paper serves to identify a number of important elements such as socialization, cultural and ecological resources and investigate the viability of rural areas. The purpose of this study is to evaluate rural amenities by evaluation indices and establish planning direction of amenities for rural areas. The data have been collected by methods of a field survey and a questionnaire survey. The evaluation indices have been defined as socialization, safety, amenity and convenience by several researches. Villages have been divided into two groups. Seven(Shimchon, Ibaek, Muan, Dokpyong-li, Imchin-li Hyangyang-li, Wonwol-li) have been newly constructed, six(baeksa, Mokmyon, yongho-li, shindyae-li, hwangdun·songgae) have been redeveloped. There are considerable differences in the degree of satisfaction between he two groups. The results are as follows: 1) socialization is very necessary for amenities in rural villages. Especially the values of the resident's interactions and management of the village are most important in the preparation of an amenity plan in rural areas. So the plans and establishment of public facilities are requisite for the residents community. 2) The convenience of rural public facility plans is necessary for the improvement of the farmers'living conditions. For planning the rural villages, special regards are paid to characteristics of the village, such as the former place of residence and occupations. 3) Newly constructed village should improve their socialization and the redeveloped types should try to get a better life for amenity and safety, The residents of the redeveloped types show relatively high degree of satisfaction with indices of resident community, living convenience facilities, and management of village. On the contrary, amenity and safety are good in newly constructed types. This study has taken into consideration the characteristics of rural villages. It makes a contribution to the redevelopment of rural villages and improves amenities in rural villages. It is recommended that more studies classify the resources of rural areas and measure amenities which are significant to city dwellers in the future.
