  • A neural network of multi layer perception type, learned by error back propagation learning rule, is generally used for the verification or clustering of similar type of patterns. When learning is completed, the network has a constant value of output depending on a pattern. This paper shows that the intensity of neuron's out put can be controlled by a function which intensifies the excitatory interconnection coefficients or the inhibitory one between neurons in output layer and those in hidden layer. In this paper the value of factor in the function to control the output is derived from the know values of the neural network after learning is completed And also this paper show that the amount of an increased neuron's output in output layer by arbitary value of the factor is derived. For the applications increased recognition performance of a pattern than has distortion is introduced and the output of partially damaged neurons are first managed and this paper shows that the reduced recognition performance can be recovered.

  • This study has analyzed the process of space information perceived and recognized through the estimation of observation frequency and number according to the time range of observation data acquired from observation experiment with the object of hospital lobby. The followings are the results analyzed at this study. First, the continual observation of 3 and 6 times was attentive and conscious for probing to find an object rather than for acquiring exact information and that of 9 times could be regarded as the time for acquiring visual appreciation. However, the repetitive occurrence of high and low frequencies can be thought of repetitive acts for visual appreciation. Second, the continual observation of 3 and 6 times had the highest observation frequency of II, while that of 9 times had the highest observation frequency of III. In case of 3 and 6 times, the observation frequency had the tendency to become a little higher after being low since V, and in case of 9 times it had the repetition of becoming low and high and from IX it characteristically got higher. This feature can be thought to be the process that the subject repeats the fixation and movement of observation at a visual activity for perception and recognition. In the process of first observation, the observation frequency was the highest after 20 seconds or so, but since then, it gets lower and repeatedly gets higher and lower as time passes. After 90 seconds, the frequency showed the tendency of getting higher continuously. Third, the examination of changing features of frequency may show the characteristics of exploration for and attention to space but if the observation frequency is not associated with observation times for analysis there will a limitation that the features of observation frequency cannot be clarified. Accordingly, the simultaneous analysis of both is very effective for estimating the observation characteristics seen at the processes of perception and recognition. Fourth, the general analysis of the both revealed: with the progress of observation time the discontinuous space exploration decreased, and as the observation time got longer the fixed attention to a specific spot increased. Fifth, in order to estimate the observation characteristics by the change of time range the observation frequency and times by trend line was analyzed, which approach seems to be an appropriate technique that can comprehensively show the overall flow of time series data.

  • The study presents preliminary research on how science activities focusing on problem recognition worked and affected students' perception of their learning environment in a sixth science classroom. The science activities were based on the Science Writing Heuristic (SWH) which was suggested by Keys, Hand, Prain & Collins (1999), where problem recognition was an important part of scientific inquiry. For developing the working sheets for the modified SWH in this study, analyses of target units of 6th grade science curriculum in the aspects of problem recognition were conducted. After consecutive 6 classes with the developed working sheets for sixth graders, the student working sheets for each lesson were collected and analyzed. In order to investigate the developed units' affect on student learning, students' perceptions of their learning environment were administered before and after the applied classes. Students working sheets and questionnaires on their perceptions of learning environment indicated that students perceived that the science activities were more student-centered classes where students had active discussion and dialogue with one another giving them more chances to actively take part in the class as well as they used more properly recognized their inquiry problem.

  • The purpose of this study was to investigate the perception of and preferences for traditional seasonal foods in Deagu & Gyeongbuk. According to surveys, females (51.2%) demonstrated a higher preference level than males (48.8%), and that for 'married' subjects was highest. Most subjects were classified as 'nuclear family', and 55.0% lived in apartment housing. The reason they experienced or gained knowledge of Korean seasonal foods was parents, which accounted for 64.4%. Reasons for liking Korean traditional drinks was 'traditional food', which scored the highest at 62.8%, followed by 'seasonal food' at 30.4%. The most common reason for disliking Korean drinks was 'lack of information'. The perception of and preferences for seasonal foods were 'rice cake soup', which scored the highest (4.85 points), followed by 'Ginseng chicken soup' (4.70 points). As a result, popularization of traditional seasonal food was based on three factors: modernization, simplicity, and awareness, which significantly influence the preference for Korean traditional seasonal foods.

  • Purpose: This study aimed to investigate the perceptions of tele-physical therapy of health and non-health majors. It can provide basic research data for the provision of medical services in the future by identifying the level of awareness of the need for tele-physical therapy and the factors that affect it. Methods: The subjects were adults aged 20 to 29 in Korea, with 199 participants consisting of 83 health majors and 116 non-health majors. The survey was conducted over a period of 14 days. The survey comprised 19 questions, including 10 questions about general characteristics and 9 questions about tele-physical therapy recognition. The results were statistically analyzed using a statistical package program. Results: There was a significant difference between the two groups regarding the recognition of tele-physical therapy, with an average of 2.64 points in health majors and an average of 1.71 points in non-health majors, showing a low overall score. There was no significant difference in perception of the necessity of tele-physical therapy, with an average of 3.71 points in health majors and an average of 3.49 points in non-health majors, showing a high score, which was defined as a score of 3 or higher. Conclusion: Health and non-health majors showed low awareness of tele-physical therapy. A high level of perceived necessity for tele-physical therapy was shown. In the perception of tele-physical therapy in health majors, 'awareness', 'health improvement', and 'convenience' affect the perception of the necessity of tele-physical therapy. In non-health majors, 'knowledge and skills', 'health improvement', 'expected treatment satisfaction', and 'resolving restrictions on hospital visits' affect the perception of the necessity of tele-physical therapy.

  • Recently, as the domestic job problem has become serious, government ministries are investing a lot of budgets to encourage startups by prospective entrepreneurs. What is important to the success of startups is the recognition of various startup opportunities before starting a startup, and the experience through trial. However, in reality, prospective entrepreneurs recognize and seek various startup opportunities through support such as startup education and initial commercialization funds through various government supported projects, but it is difficult to actually start a business. Previous studies have revealed that the recognition of entrepreneurial opportunities affects entrepreneurial intentions by various variables such as gender, but research is insufficient on what kind of black box exists between the recognition of entrepreneurial opportunities and entrepreneurial intentions. The purpose of this study is to emphasize the importance of positive psychological capital as a major method for improving the entrepreneurial intention, and to analyze exploratorily whether positive psychological capital plays a mediating role between the recognition of entrepreneurial opportunities and the entrepreneurial intention. As a result of the study, it was confirmed that the recognition of startup opportunities affects the intention to start a business, and positive psychological capital has a mediating effect between the recognition of the startup opportunity and the intention to start a business. This means that positive psychological capital is important in order to lead to actual entrepreneurial intentions after recognizing a startup opportunity. Therefore, in order to revitalize the startups of prospective entrepreneurs in the current startup ecosystem, it is necessary to prepare a plan to improve the recognition of startup opportunities and positive psychological capital.

  • Perception of surfaces from range images plays a key role in 3-D object recognition. Recognition of 3-D objects from range images is performed by matching the perceived surface descriptions with stored object models. The first step of the 3-d object recognition from range images is image segmentation. In this paper, an approach for segmenting 3-D range images into symbolic surface descriptions using spatial Gabor filter is proposed. Since the phase of data has a lot of important information, the phase information with magnitude information can effectively segment the range imagery into regions satisfying a common homogeneity criterion. The phase and magnitude of Gabor filter can represent a unique featur vector at a point of range data. As a result, range images are trnasformed into feature vectors in 3-parameter representation. The methods not only to extract meaningful features but also to classify a patch information from range images is presented.
