Extracting information of maps is necessary to establish the GIS. In this paper, a house recognition method on the scanned topographic map is described. A contour detection method is used to extract houses from the scanned maps and RLE (run-length encoding) method is used for manipulating houses touching grid lines. To handle houses touched to roads and borderlines, morphological operation is used. To remove misrecognition occurred by morphological operation, the legions which contain characters on the map are also automatically eliminated.

In this paper, we applied the high-performance PGAP(Parallel Genetic Algorithm Processor) to recognizing rotated pattern. In order to perform this research efficiently, we used Multi-PGAP system consisted of four PGAP. In addition, we used mental rotation based on the rotated pattern recognition mechanism of human to reduce the number of operation. Also, we experimented with distinguishing specific pattern from similar coin patterns and determine rotated angle between patterns. The result showed that the development of future artificial recognition system is feasible by employing high performance PGAPS.

We propose a hand gesture recognition method that is compatible with a head-up display (HUD) including small processing resource. For fast link adaptation with HUD, it is necessary to rapidly process gesture recognition and send the minimum amount of driver hand gesture data from the wearable device. Therefore, we use a method that recognizes each hand gesture with an inertial measurement unit (IMU) sensor based on revised correlation matching. The method of gesture recognition is executed by calculating the correlation between every axis of the acquired data set. By classifying pre-defined gesture values and actions, the proposed method enables rapid recognition. Furthermore, we evaluate the performance of the algorithm, which can be implanted within wearable bands, requiring a minimal process load. The experimental results evaluated the feasibility and effectiveness of our decomposed correlation matching method. Furthermore, we tested the proposed algorithm to confirm the effectiveness of the system using pre-defined gestures of specific motions with a wearable platform device. The experimental results validated the feasibility and effectiveness of the proposed hand gesture recognition system. Despite being based on a very simple concept, the proposed algorithm showed good performance in recognition accuracy.

For each character constituting learning data, different fonts are added in pixel unit to create MASK, and then pixel values belonging to the MASK are divided into three groups. The experimental data are modified into skeletal forms, and then regional boundary operation is used to create a boundary that distinguishes the background region adjacent to the skeleton of the character from the background of the modified experimental data. Discordance values between the modified experimental data and the MASKs are calculated, and then the MASK with the minimum value is found. This MASK is selected as a finally recognized result for the given experiment data. The recognition algorithm using skeleton of the character and the regional boundary operation can easily extend the learning data set by adding new fonts to the given learning data, and also it is simple to implement, and high character recognition rate can be obtained.

This study analyzed relation with risk recognition degree by customs business of customs brokers and actuality insurance accident occurrence. These study finding that risk recognition by customs work area of customs brokers and actuality insurance accident occur did not agree. So customs brokers more elevate risk recognition of entry field, origin/trademark right, HS and customs tariff application, customs refund, price estimation that are high the insurance accident rate. and they may have to do emphasis administration through employee education and ability elevation. Specially, operation risk that is produced from charge employee's simplicity mistake who tax invoice omission, a tax use mistake, document nondelivery, notice dispatch delayed action, may have to manage through moral management and employee bylaws and education, employee guidance etc. Also, they publicize these contents to import and export enterprise, and practice risk management of high risk business in priority through education and public information. so we will have to make can do more effective risk management.

WiSee is by utilizing the frequency of Wi-Fi(802.11n/ac), a technique for performing the operation recognized by the user's gesture. Current motion recognition scheme are using a dedicated device (leaf motion, Kinekuto) and the recognition range is 30cm ~ 3.5m. also For recognition range increases the narrow recognition rate, there is inconvenience for maintaining a limited distance. But WiSee is used by Wi-Fi it is possible to anywhere motion recognition if available location. Permeability also has advantages as compared with the conventional recognition method. In this paper I take a look at the operation process and the recent trend of WiSee.

This study analyzed purchasing characteristics of local agricultural products and processed products as well as evaluated operation programs for Changnyeon festival participants. The purchasing rates of local agricultural products and processed products at this festival were 63.6% and 49.1%, respectively, and the main purchased crops were onion (42.6%) and garlic (20.7%). Drinks (43.6%) were highly purchased processed products. The recognition (95.3%) and preferences (98.4%) for Changyeong local agricultural products were high at this festival. Subjects (72.5%) responded that public relations were effective for sale at this festival, and evaluation of the operation program for the festival was $3.51{\pm}0.74$ (total score 5 points). Satisfaction with the experience event (37.7%) and exhibition event (33.6%) were high at this festival program, whereas participants gave low rates for art exhibition and sale events of local agricultural products (16.2%), cooking education (14.7%), direct education program (12.9%), and games (12.1%). This festival was an effective means of public relations, although purchase effects were not significant. This result suggests that the festival is necessary for planning a program to increase purchasing.

This study is to help international traders in conducting tax and accounting works as to revenue recognition when a shipment incurs in accordance with Incoterms 2010. It is true that some are well familiar with Incoterms but have lack of accounting and tax application. In respect of tax operation, there are several regulations, such as Income Tax Law, VAT Law, which are applied differently according to sales points. Sales points and revenue recognition are a bit different when sales are made internationally. And this study compares those revenue recognitions by comparison of related Korean laws and Incoterms 2010.

A challenging research issue that has been one of growing importance to those working in human-computer interaction are to endow a machine with an emotional intelligence. Thus, emotion recognition technology plays an important role in the research area of human-computer interaction, and it allows a more natural and more human-like communication between human and computer. In this paper, we propose the multimodal emotion recognition system using face and speech to improve recognition performance. The distance measurement of the face-based emotion recognition is calculated by 2D-PCA of MCS-LBP image and nearest neighbor classifier, and also the likelihood measurement is obtained by Gaussian mixture model algorithm based on pitch and mel-frequency cepstral coefficient features in speech-based emotion recognition. The individual matching scores obtained from face and speech are combined using a weighted-summation operation, and the fused-score is utilized to classify the human emotion. Through experimental results, the proposed method exhibits improved recognition accuracy of about 11.25% to 19.75% when compared to the most uni-modal approach. From these results, we confirmed that the proposed approach achieved a significant performance improvement and the proposed method was very effective.

The purpose of this study is to reveal working time and psychological difficulties of national and public daycare center teachers in the operation process of an accreditation system and seek ways of resolving them. For this purpose, a survey was conducted on 413 teachers in 291 national and public daycare centers in Seoul, Gyeonggi, and Incheon, and in-depth interviews were conducted with 7 nursery teachers. It showed that in the operation process of an accreditation system, teachers had been performing heavy tasks of 11 hours daily, and they were experiencing psychological difficulties with the conflict 'between interactions with infants and other duties', 'between free exploration and safety health', and 'between our story and external criteria'. Based on the findings, the following changes of recognition for nursery teachers were required. First, there is a need for the change of recognition concerned with the child-care of high quality, rather than performing evaluation index. Second, there is a need for the change of recognition concerned with overall optimization rather than sectional optimization. This study is significant in that it suggested the basic direction for the operation process of an accreditation system, by exploring the psychological difficulties of nursery teachers.
