Main elements in definition of space value were physical, formal, and reasonable characteristics in the past. Howener recently, definition of space value is changing by being advanced about study concerned with human's cognition and thinking way in definition and analysis of space. As you see, cognitive psychologists have emphasized the importance of human's cognitive structure and process and studied diverse aspects of human's thinking ; consciousness, perception, memory, image, language, decision-making, inference, and so on. Therefore main elements in definition of space value are five-dimensional, psychological, symbolic, mental, emotional characteristics above physical, formal, and reasonable characteristics. As mentioned above, the conversion of thinking focused on reason to thinking focused on human's spirit and emotion is achieved in contemporary architecture and 'human's experience' in space becomes a very important factor. For that reason, the purpose of this study is consideration of human's cognitive process in space by conversion of thinking and gives a definition about experience. And, I would like to define 'experience design' whose main attribute is experience in space and establish theoretical basis of experience design through theoretical researches about experience. This study on experience design that induces users to participate in space and stimulate human's spirit is a important point in definition of space value not only contemporary interior architecture but also prospective generation.

KMA is operationally monitoring El Ni$\tilde{n}$o and La Ni$\tilde{n}$a events, which have tremendous impacts on global climate. Many scientific studies have used to define onset of El Ni$\tilde{n}$o and La Ni$\tilde{n}$a events based on the moving average and persistency of SST indices, and KMA has adopted such definition. Though the definition has been widely accepted, in the operational aspect there is a critical problem to use moving average and condition for the persistence. Because the future values for the SST indices cannot be used in the operational monitoring, the onset timing in El Ni$\tilde{n}$o and La Ni$\tilde{n}$a can be significantly delayed. We suggest here an appropriate definition of El Ni$\tilde{n}$o and La Ni$\tilde{n}$a events in the operational aspect. Instead of using the moving average and the condition for the persistence, the onset is defined based on NINO3.4 SST during last 3 months. In order to compare the new definition with the current KMA definition, we applied them to recent 60-years SST data. It is clear that the new definition can declare the onset timing of El Ni$\tilde{n}$o and La Ni$\tilde{n}$a several months earlier than that of the KMA definition. It suggest that the new definition is more appropriate to the operational monitoring on El Ni$\tilde{n}$o and La Ni$\tilde{n}$a.

In this study, we consider the informal and formal definition of limit on the basis of middle and high school curriculum, and then analyze the reason of difficulties experienced when sophomores learn the formal definition(${\epsilon}-{\delta}$ procedure) of limit. We conducted teaching of the formal definition of limit with sophomores and analyzed their errors which were appeared when they applied to limits problems. In addition, we try to improve the understanding of ${\epsilon}-{\delta}$ procedure of the limit taught in analysis.

This paper was designed for the purpose of helping the functional comprehension on the concept of a circumcenter and an incenter of triangle and offering the help for teaching-learning process on their definitions. We analysed the characteristic of the definition on a circumcenter and an incenter of triangle and studied the context, mean and purpose on the definition. The definition focusing on the construction is the definition stressed on the consistency of the concept through the fact that it is possible to draw figure of the concept. And this definition is the thing that consider the extend of the concept from triangle to polygon. Meanwhile this definition can be confused because the concept is not connected with the terminology. The definition focusing on the meaning is easy to memorize the concept because the concept is connected with the terminology but is difficult to search for the concept truth. And this definition is the thing that has the grounds on the occurrence but is taught in a made-knowledge. The definition focusing on both the construction and meaning is the definition that the starting point is vague in the logical proof process. We hope that the results are used to improve the understanding the concept of a circumcenter and an incenter of triangle in the field of mathematical education.

As high-definition video is broadly used in various system such as broadcast system and digital camcorder the proper method in order to improve the quality of high-definition video is needed. In this paper, we propose an efficient method to improve color and contrast of high-definition video. In order to apply the image enhancement method to high-definition video, scale-down video of high-definition video is used and the parameter for image enhancement method is computed from small size video. To enhance the color of high-definition video, we apply color constancy method. First, we separate the video into several scenes by cut detection method. Then, we apply color constancy to each scene with same parameter. To improve the contrast of high-definition video, we use union of original image and histogram equalized image, and weight is calculated based on sorting of histogram bins. Finally, the performance of proposed method is demonstrated in experiment section.

Objectives : This study was to analyze the definitions of herbs, herbal drugs, crude drugs and natural products in the relevant laws and regulations, understand the related problems, and propose directions for improvement. Methods : I analyzed the legal definitions in respect of herbs, herbal drugs, crude drugs and natural products in relevant laws and regulations since 1945, explained the problems, and suggested the solution-considering the academic stance of Traditional Korean Medicine and the dualistic medical and pharmaceutical system. Results : Herbs are defined as "refined things that are cut and dried in their most original state". The definition of crude drugs includes herbs and the "cell contents, secretion, extracts, minerals and other parts of animals and plants that are used medicinally". The concept of natural products is expanded to adding tissue cultures to the definition of crude drugs. Conclusions : The definition of herbs should at least include all products that are "processed, extracted and prepared" as well as contents that consist of various forms of hospital-prepared herbs. The term "herbal drug" corresponds to a traditional term of "drug", and this should be established as a concept to explain "drugs in raw materials that are used to prepare herbs and/or manufacture herbal medicine". The legal definition of herbs should include the concept of crude drugs. Herbal drug preparations and crude drugs should be included in the definition of herbal drugs.

The purpose of this study was to investigate university students' motivation for parenthood related to their definition of parenthood, empathy and self-esteem. Participants were 447 junior and senior students(male 263, female 184) in 5 universities throughout Korea. Results were : (1) Male students and employed mothers were higher than female students and unemployed mothers' 'motivation for strengthening biological family ties' but there were reversed results in 'motivation for traditional norms.' Students majoring in home economics showed the highest score in 'altruistic-emotional motivation.' (2) There were positive correlations between motivation for parenthood and definition of parenthood and empathy. 'Motivation for traditional norms' correlated positively with self-esteem. (3) Motivations for parenthood were explained by about 4~28% by their definition of parenthood, empathy, and self-esteem.

Disability Discrimination Act(DDA) is generally recognized as the institutional frame to realize social model of disability. However social model is not automatically realized via the enactment of DDA. The realization of social model is influenced by various factors among which the definition of disability in DDA is very important factor. Paradoxically definitions of disability based on social model may push DDA into contradictory situation. This is caused by the fact that on the one hand definitions of based on social model exclude impairment and on the other hand they mixes characteristics and treatment. Because of these, when definitions of disability based on social model is reflected into definitions of disability in DDA, they may not be helpful to realize social model against original intention of advocates of the model. We can consider two approaches to resolve this paradox; one is to partially reform current definition of disability in DDA, the other is to totally amend current definition of disability. The former may pragmatic and worth to pursue but it cannot solve fundamental problems and may cause some new problems. The most consistent resolution with social model is to amend current definitions of disability into radically new one which excludes substantial limits and definition of disabled person from definition of disability. This new definition may called characteristics based definition or impairment based definition. Some people may think this new definition as one based on medical model but it is not. What we need is not to carve definition of disability based on social model into DDA but to make institutional frame for DDA to operate without contradictions and to develop social model of both impairment and disability. This model which does not exclude impairment could takes part in realization of the social model disability.

Differing from civil engineering and construction, landscape architecture projects are far from efforts in operation and project management. Under the circumstances, it is worthwhile to adopt scope definition from project management for construction and civil engineering in some respects. First, scope definition is able to be conducted through a simple procedure without additional investment in capital and time. Second, the output produced by scope definition is very substantial. The research scrutinized scope definition procedures accompanied by landscape architecture project execution and derived various methods in order to help scope definition for efficient landscape architecture projects. Based on the literature review, a design case study, and an exert interview, the project success elements were developed consisting of 3 sections, 8 categories and 50 elements, grounded on the theoretical base of PDRI. The elements are expected to pave a way to an adequate level of scope definition among participants of landscape architecture projects and contribute in efficient project execution.
