Just as culture is a collection of lifestyles, Cultural Properties is what is made over a long period of time and is left around us, whether it takes form or not. Many countries around the world have their own standards and are trying hard to preserve those with precious values. And in the case of Modern Architecture, because they are still in use In our daily lives and for the lack of recognition, they are continuously threatened during urban changes and developments. The purpose of the research is not to preserve Modern Architecture as done In the museum, but to seek a way for it to coexist with the changing environments of contemporary cities. Therefore, it is to recognize Modern Architecture as valuable assets, which expresses historicity in urban settings, and to seek the design characteristics of Modern Architecture. This is a process in order to find a new method for conservation of historicity. The result are as followings. Modern Architecture have their design characteristics and these can be applied as a design guideline. Therefore the form, material, and the colors of individual Modern Architecture can be analyzed so as to create a design guideline according to their styles. According to the analysis of Registered Cultural Properties in Seoul, they can be categorized into 6 uses and found the design characteristics of individual uses.

In Korean apartment housing, balcony is semi-outdoor space for storage and drying laundry. Recently, this semi-outdoor balcony space has been merged into indoor living space with the legal permission of balcony extension. It results in disappearance of the original function of balcony in apartment housing. This study attempts to propose better utilization of balcony extension by analyzing how balcony has been extended and used, and what residents' needs are. This study asks 400 housewives living in apartment housing in Jangyu new urban area, Kyungnam. Findings are : 1) Balcony extensions are carried out in a living room, a large bedroom and a small bedroom. Most extensions are made for enlarging adjacent indoor living space; 2) Original balcony that is not extended is used for drying laundry, resting, flower pot, storing, and kid's playing; 3) The residents recognize that problems of balcony extension are the decreased heating efficiency, the reduced soundproofing effect, the loss of spare housework space, and the disappearance of buffer between indoor and outdoor space; 4) Many residents want to extend their balcony space of a small bedroom and a large bedroom and to keep the balcony space of a kitchen-dining room and a master bedroom as they are.

Urban is made over a long period of time. In the process, architecture involves design characteristics of age and place. In the case of modem western style architecture, just depend on the economic logic, they are continuously threatened during urban changes. Therefore, the purpose of this paper is to recognize modern western style architecture as valuable things, which represents color of urban, and to seek how it can be reused. This is a process in order to find a new method for conservation and reuse of modern western style architecture. The result are as followings. Modern western style architecture must be recognized as resource, which expresses identity of urban, and found a method for conservation and reuse of facade at least. So we need to search design characteristics of facade. It has been analyzed that assigned modem western style architecture in seoul can be divided into 6 groups. Each group has individual characteristics of facade expression, which is 'dormer', 'vent', 'balustrade', 'cornice', 'dome', 'tower', etc in top part, and 'the shape of window and door', 'the element of ornament', 'finish', etc in middle part.

A face recognition is currently the field which many research have been processed actively. But many problems must be solved the previous problem. First, We must recognize the face of the object taking a location various lighting change and change of the camera into account. In this paper, we proposed that new method to fund feature within fast and correct computation time after scanning PC camera and ID card picture. It converted RGB color space to YUV. A face skin color extracts which equalize a histogram of Y ingredient without the luminance. After, the method use V' ingredient which transformes V ingredient of YUV and then find the face feature. The reult of the experiment shows getting correct input face image from ID Card picture and PC camera.

In general, we have used the Viterbi algorithm of Speech recognition for decoding. But a decoder in speaker verification has to recognize same word of every speaker differently. In this paper, we propose a noble decoding algorithm that could replace the typical Viterbi algorithm for the speaker verification system. We utilize for the proposed algorithm the speaker adaptation algorithms that transform feature vectors into the region of the client' characteristics in the speech recognition. There are many adaptation algorithms, but we take MLLR (Maximum Likelihood Linear Regression) and MAP (Maximum A-Posterior) adaptation algorithms for proposed algorithm. We could achieve improvement of performance about 30% of EER (Equal Error Rate) using proposed algorithm instead of the typical Viterbi algorithm.

Hierarchical constraints and constraint satisfaction were analyzed in order to solve the problem of conflict detection in collaborative design. The constraints were divided into two sets: one set consisted of known constraints and the other of unknown constraints. The constraints of the two sets were detected with corresponding methods. The set of the known constraints was detected using an interval propagation algorithm, a back propagation (BP) neural network was proposed to detect the set with the unknown constraints. An immune algorithm (IA) was utilized to optimize the weights and the thresholds of the BP neural network, and the steps were designed for the optimization process. The results of the simulation indicated that the BP neural network that was optimized by IA has a better performance in terms of convergent speed and global searching ability than a genetic algorithm. The constraints were described using the eXtensible Markup Language (XML) for computers to be able to automatically recognize and establish the constraint network. The implementation of the conflict detection system was designed based on constraint satisfaction. A wind planetary gear train is taken as an example of collaborative design with a conflict detection system.

Epileptic Seizure is a popular brain disease in the world. It affects the nervous system and the activities of brain function that make a person who has seizure signs cannot control and predict his actions. Based on the Electroencephalography (EEG) signals which are recorded from human or animal brains, the scientists use many methods to detect and recognize the abnormal activities of brain. Tucker model is investigated to solve this problem. Tucker decomposition is known as a higher-order form of Singular Value Decomposition (SVD), a well-known algorithm for decomposing a matric. It is widely used to extract good features of a tensor. After decomposing, the result of Tucker decomposition is a core tensor and some factor matrices along each mode. This core tensor contains a number of the best information of original data. In this paper, we used Tucker decomposition as a way to obtain good features. Training data is primarily applied into the core tensor and the remained matrices will be combined with the test data to build the Tucker base that is used for testing. Using core tensor makes the process simpler and obtains higher accuracies.

As a result to amplifying 12 samples of 'Sok-dan' through an random amplified polymorphic DNA (RAPD) method using eighteen DEC and URP primers, distinct band forms enabling discrimination of Phlomus umbrosa and Dipsacus asperoides were observable in the UBC 320 primer, UBC 367 primer, UBC 385 primer, UBC 414 primer, UBC 423 primer, URP 3 primer, URP 5 primer and URP 9 primer. The polymorph result amplified with a random primer was evaluated through Gelcompar II, showing a result dividable into two groups. The divided groups were the dried sample group of Dipsacus asperoides and the group of Phlomis umbrosa. In order to recognize the distinction between Dipsaci Radix types, the genetic variation of 'Sok-dan' produced domestically and imported was evaluated through RAPD, and the potential to distinguish these in forms of dried medicine was identified, presenting a method to authentification of Phlomis umbrosa and Dispacus asperoides.
