Land development policy in Korea, characterized by its supply-oriented policy, has driven rapid economic development. However, it has a negative impact on the natural environment across the country. Especially, as the introduction of quashi-farmland system with the deregulation of agricultural land development in the late 1990s, numerous unfavorable landscape features such as road, motels and apartment have emerged in the rural area. As those interfered irreversible rural landscapes have been expanded, the demand for well preserved rural landscapes have been increased. The objectives of this study, thus, is to suggest the mitigations between the land development and conservation of natural landscape. As such, this study examines the recognition of current rural landscape management status through 118 students with two groups of landscape architecture majored (50 people) and non-landscape majored (68). Both group express the negative impression of current rural landscape management system in general and they pointed out the major landscape problems are caused from inappropriate land use. However, in detail those two groups respond differently, for example, the first group selected the damaged landscape is the second cause of the landscape problem, while the other group selected the poorly maintained settlements. Based on the analysis of the survey, this study suggests 3 recommendations in order to improve the sustainable rural landscape as establishing the proper rural land use planning system, building local governments' capacity to actively participate in the rural landscape management, and preparing the landscape management plans considering area distinctive characteristics.

In this paper, we propose HMM-based upper-body gesture. First, to recognize gesture of space, division about pose that is composing gesture once should be put priority. In order to divide poses which using interface, we used two IR cameras established on front side and side. So we can divide and acquire in front side pose and side pose about one pose in each IR camera. We divided the acquired IR pose image using SVM's non-linear RBF kernel function. If we use RBF kernel, we can divide misclassification between non-linear classification poses. Like this, sequences of divided poses is recognized by gesture using HMM's state transition matrix. The recognized gesture can apply to existent application to do mapping to OS Value.

Digital signage takes the role of promotion, providing information, art and game as it is installed in various forms everywhere such as the road, subway and indoor space we pass through. The related researches also focus on the technology of realizing digital signage, current industrial state and prospect in most cases. On the contrary, the researches on the spaciality of digital signage is a kind of insufficient, this study was carried out based on the judgment that there is necessity of researching it in respect that the recognition of space by the people in there is different before and after digital signage is located in such space. First, in order to understand digital signage, its concept, type and kind were investigated, general theories about the spaciality were considered after that, the spaciality of digital signage was grasped by 5 factors such as hybridity, vitality, mobility, flexibility, and contingency and their characteristics were offered in this study. In its conclusion, it was appealed that the change of spatial recognition along media and continuous research are required as digital signage is the transactive space.

Facial expressions provide significant clues about one's emotional state; however, it always has been a great challenge for machine to recognize facial expressions effectively and reliably. In this paper, we report a method of feature-based adaptive motion energy analysis for recognizing facial expression. Our method optimizes the information gain heuristics of ID3 tree and introduces new approaches on (1) facial feature representation, (2) facial feature extraction, and (3) facial feature classification. We use minimal reasonable facial features, suggested by the information gain heuristics of ID3 tree, to represent the geometric face model. For the feature extraction, our method proceeds as follows. Features are first detected and then carefully "selected." Feature "selection" is finding the features with high variability for differentiating features with high variability from the ones with low variability, to effectively estimate the feature's motion pattern. For each facial feature, motion analysis is performed adaptively. That is, each facial feature's motion pattern (from the neutral face to the expressed face) is estimated based on its variability. After the feature extraction is done, the facial expression is classified using the ID3 tree (which is built from the 1728 possible facial expressions) and the test images from the JAFFE database. The proposed method excels and overcomes the problems aroused by previous methods. First of all, it is simple but effective. Our method effectively and reliably estimates the expressive facial features by differentiating features with high variability from the ones with low variability. Second, it is fast by avoiding complicated or time-consuming computations. Rather, it exploits few selected expressive features' motion energy values (acquired from intensity-based threshold). Lastly, our method gives reliable recognition rates with overall recognition rate of 77%. The effectiveness of the proposed method will be demonstrated from the experimental results.

In this paper, we introduce a method of selection for the optimal transmission polarization of a W-band seeker through the extraction of the one-dimensional scattering center of a ground tank target. We calculated the surface scattering and edge scattering using the shooting and bouncing ray tracing method of the CST A-solver. Based on 4-channel RCS data, using the one-dimensional RELAX algorithm, which is a kind of spectral estimation technique, scattering centers of ground targets were extracted. According to the changes in the polarization state and look angle, we compared and analyzed the scattering center results. Through simulation, we verified that the scattering center results can be applied when feature vectors are used for target recognition.

Combination of mental stress task with noise background is a traditional tool employed in psychophysiology. However, intensity of background noise is a factor affecting both performance on test and psychophysiological responses associated with stress evoked by mental load in noisy environment. In the current study on 7 subjects we analyzed the influence of white noise (WN) intensity (55, 70, and 85 dB[A] ) on psychophysiological responses during word recognition test performed on noise background. There were recorded following physiological variables: electrodermal activity (EDA) , namely, skin conductance level (SCL), skin conductance response (SCR) amplitude (SCR-A), rise time and total number of SCRs (N-SCR); cardiovascular activity, e.g., heart rate (HR), respiratory sinus arrhythmia (RSA) index, pulse transit time (PTT), finger pulse volume (PV), skin temperature (SKT) and respiratory activity, such as respiration rate (RESP-R) and inspiration wane amplitude (RESP-A) during baseline resting state and 40 s long performance on 3 similar Korean word recognition tests with different WN intensity (55, 70, and 85 dB). Electrodermal responses (SCR-A, SCL, N-SCR) demonstrated gradual increment with increased intensity of noise, and this increase of response magnitude with higher intensity of noise was typical also for r skin temperature (phasic SKT decrease) and pulse volume (phasic and tonic PV decrease). However, some cardiovascular and respiratory responses did not exhibit same tendency of gradual increase of reactivity , namely HR, as well as RESP-R and RESP-A showed decrement of response magnitudes. Important finding in terms of cardiovascular reactivity was that 55 and 70dB evoked similar profiles, while 85dB WN resulted in significantly different profile of reactions, suggesting that there exists a threshold level after which intensive auditory stimulation elicits psychophyslological responses pattern of different quality. There are discussed potential autonomic mechanism involved in mediation of observed physiological responses.

The purpose of this study was to develop a program of oral health education for children and to furnish basic data contributing to the improvement of children's oral health. In this study, we tried to analyze and discover the types of recognition in parents of children's oral care. With the use of Q-methodology that could systematically and scientifically estimate the subjectivity of humans, 28 parents were collected as a P-sample. 3 general types were discovered. The characteristics of each type were the following: Type 1. "Serious consideration of prevention care type" took a positive attitude to their children's oral care, were knowledgable, and maintained high concern about oral care. They regularly visited dentists for prevention and believed in caries prevention through brushing teeth. They also put high trust in dentists. Type 2. "Disposition by the existing state type" believed that caries could develop even with brushing teeth and could be inherited from parents, Practically, they had a passive attitude to their children's oral care depending on stages and were more concerned with the appearance of dentition than with their children's oral health. Type 3. "Home care-centered type" had less knowledge about children's oral care than the other two types and was careless for teeth prevention. Therefore, they had not intended to participate in the oral health education program.

The obligation on a national court to recognize and enforce arbitral awards as provided in Article III New York Convention, which both Korea and China have ratified, is subject to limited exceptions. Recognition and enforcement will be refused only if the party against whom enforcement is sought can show that one of the exclusive grounds for refusal enumerated in Article V(1) New York Convention has occurred. The court may also refuse enforcement ex officio if the award violates that state's public policy. This article explores the circumstances where arbitral awards may be refused enforcement under the Korean and Chinese arbitration laws. It first analyzes the relevant statutory provisions. In Korea and China, which have adopted the UNCITRAL Model law, the grounds of challenge are exhaustively defined within their respective arbitration laws. According to their arbitration laws, an arbitral award may be set aside if a party making the application proves that (i) a party to the arbitration agreement was under some incapacity or the agreement is not valid under the applicable law, (ii) the party making the application was not given proper notice of the appointment of an arbitrator or of the arbitral proceedings or was otherwise unable to present his case, (iii) the award deals with a dispute not contemplated by or not falling within the terms of the submission to arbitration or contains decisions on matters beyond the scope of the submission to arbitration, or (iv) the composition of the arbitral tribunal or the arbitral procedure was not in accordance with the agreement of the parties. An arbitral award may also be set aside ex officio by the court if the court finds that (i) the subject-matter of the dispute is not capable of settlement by arbitration under the applicable law or (ii) the award is in conflict with the public policy. This article then reviews relevant judicial decisions rendered in Korea and China to see how the courts in these countries have been interpreting the provisions specifying the grounds for challenging arbitral awards. It concludes that the courts in Korea and China rarely accept challenges to arbitral awards, thereby respecting the mandate of the New York Convention.
