This paper presents the sound-based emotion estimation method and the growing HRI (human-robot interaction) system for a Mon-E robot. The method of emotion estimation uses the musical element based on the law of harmony and counterpoint. The emotion is estimated from sound using the information of musical elements which include chord, tempo, volume, harmonic and compass. In this paper, the estimated emotions display the standard 12 emotions including Eckman's 6 emotions (anger, disgust, fear, happiness, sadness, surprise) and the opposite 6 emotions (calmness, love, confidence, unhappiness, gladness, comfortableness) of those. The growing HRI system analyzes sensing information, estimated emotion and service log in an edutainment robot. So, it commands the behavior of the robot. The growing HRI system consists of the emotion client and the emotion server. The emotion client estimates the emotion from sound. This client not only transmits the estimated emotion and sensing information to the emotion server but also delivers response coming from the emotion server to the main program of the robot. The emotion server not only updates the rule table of HRI using information transmitted from the emotion client and but also transmits the response of the HRI to the emotion client. The proposed system was applied to a Mon-E robot and can supply friendly HRI service to users.

This paper explores the impact of pollution abatement cost on trade balance. First, We derive price pressure of spending pollution abatement cost using I-O table. Then the analysis is extended to the impact on trade balance by manufacturing sectors. The paper explicitly includes indirect effect of pollution abatement cost that is the effect through the change of the other sector prices and excluded in the previous studies. The results show that the impact of pollution abatement cost on trade balance is 0.30~0.46% of total trade volume of Korea. This is lower than that of the United States in 1970's.

Objectives: The objectives of this study are to determine both what information Korean Medicine(KM) doctors want from medical classics and how classic KM knowledge should be structured. Methods: KM doctor survey was conducted in October 2012 via E-mail to determine what information Korean Medicine doctors want to collect from a larger volume of existing classics. Specialist survey was made in October 2012 through questionnaire and 8 workshops were held between April 2012 ~ February 2013 to discuss how to reorganize classic KM knowledge. Results: With two surveys and 8 workshops, we built a conceptualization of the classic KM knowledge system for KM practice. KM doctors wanted to engage with the design of KM knowledge system informed by authentic medical classics, and hoped that more information on common disorders would be added to the table of contents of classic KM books than now. A comprehensive knowledge system was also required to maximize information sharing. Conclusions: Future KM knowledge systems need to be more comprehensive and include more information about disorders with which patients commonly consult KM doctors.

This study was designed to establish Korean food culture by analyzing 17 sets of Jinyounuigue, Jinchanuigue, and Jinjarkuigue which were the records of royal party procedures in Yi dynasty, Analysis was made on royal parties in terms of table setting, kinds of dishes served, composition of foods, frequency of the food materials used, and food items changed over the period from 1719 to 1902, the latter half period of Yi dynasty. Foods used in those parties were classified into seven groups in this study; rice and noodoes, side dishes, Docks, desserts, fruits and nuts, beverages, and sauces. There were about 10 kinds of steamed rice and noodles including Mandoo and Byungtang, 140 different kinds of side dishes, 53 kinds of Kocks, 142 kinds of various desserts, especially Dasik and Korean cookies, 38 kinds of fruits and nuts, 10 kinds of beverages including Hwachae and Sujeongkwa, and 10 kinds of sauces such as soy sauce, mustard, honey, and etc. There was no tendency in omission or addition of food materials, but the number and heights of dishes were designated by the scale or character of the party. There were unique measuring units that were quite different from metric system. More than 30 different units were appeared in the differences. Most of them were used for typical items such as Sari for noodles only. However some were quite general and used until now. Mal and Dye were the units for volume, Kwan and Kuen for weight, and Chock and Chon for length.

20th century, beginning of modern, the style of art and design, separated reasonable and sensitive code. Art form including cubism, constructivism, futurism and different form including fauvism, expressionism, surrealism and abstract expressionism coexist two code in early modern. But the style of design was separated each period with geometric and organic form, reasonable and sensitive code. Replacement timing on two design style was the transition period of the production-oriented step to the sale-oriented step in marketing. In early stage modern it was stable production-oriented step. Geometric style include G. Rietvevld (Red and Blue chair), M. Breuer (Wassily chair), Fanizon and Martinelli (I-Ching) was simple and functional, received the absolute support. An aggressive demand generation and sales promotion for the design change was needed so that excess supply in the market with a stable production. In sale-oriented step for sales promotion in mid modernism, it was accepted transitions to the sensual organic volume with elegant and sleek style include C. Eames (LCW chair), V. Panton (Panton chair) and C. Mollino (Arabesco Tea table).

The hydrological simulation program FORTRAN (HSPF) is a comprehensive watershed model that employs the hydraulic function table (FTABLE) (depth-area-volume-flow relationship) to represent the geometric and hydraulic properties of water bodies. The hydraulic representation of the HSPF model mainly depends on the accuracy of the FTABLES. These hydraulic representations determine the response time of water quality state variables and also control the scour, deposition, and transport of sediments in the water body. In general, FTABLES are automatically generated based on reach information such as mean depth, mean width, length, and slope along with a set of standard assumptions about the geometry and hydraulics of the channel, so these FTABLES are unable to accurately describe the geometry and hydraulic behavior of rivers and reservoirs. In order to compensate the weakness of HSPF for hydraulic modeling, we generated alternate method to improve the accuracy of FTABLES for rivers, using the surveyed cross sections and rating curves. The alternative method is based on the hydraulics simulated by HEC-RAS using the surveyed cross sections and rating curves, and it could significantly improve the accuracy of FTABLES. Although the alternate FTABLE greatly improved the hydraulic accuracy of the HSPF model, it had little effect on the hydrological simulation.

The purposes of this study are to make an analysis the sensible degree in Korea by using the formulas prepared by Watanabe, and to divide the climatic classification by the sensible degree in order to apply in practical life. Most data(air temperature, relative humidity, wind velocity, atmospheric pressure) are extracted from the "Climatic Table of Korea, Volume II(1961~1990)" issued by the Korea Meteorological Administration. As a result of this study, distribution patterns of the sensible degree are similar to isotherms when the wind velocity is zero, and then the sensible degrees are reduced with the increase of latitude. And western coastal and inland regions have larger values than eastern coastal regions in summer. However, the cont-rary distributions are shown in winter. When the wind velocity is not zero, distribution patterns of the sensible degree are influenced by the wind velocity. In summer, the values of central and southern inland regions are especially higher than the coastal regions, and most northern districts and some inland regions (Kangnung, Ulchin, Yongju etc.) have low values in winter. Then, the climate of Korea is divided into four patterns as follows : Yow means the sensible degree when the wind velocity is zero in winter. Yow > 3 : Jeju Island and southern coastal regions Yow = 0~3 : Most southern district and eastern coastal regions of central districts Yow = -3~0 : Most central districts and some eastern coastal regions (Hamheung, Youngheung, Won-san etc.) of northern districts Yow < -3 : Most northern districts and some inland regions(Inje, Hongcheon, Yang-pyeong etc.) of cent-ral districts.districts.

Network anomaly detection in Software Defined Networking, especially the detection of DDoS attack, has been given great attention in recent years. It is convenient to build the Traffic Matrix from a global view in SDN. However, the monitoring and management of high-volume feature-rich traffic in large networks brings significant challenges. In this paper, we propose a moving window Principal Components Analysis based anomaly detection and mitigation approach to map data onto a low-dimensional subspace and keep monitoring the network state in real-time. Once the anomaly is detected, the controller will install the defense flow table rules onto the corresponding data plane switches to mitigate the attack. Furthermore, we evaluate our approach with experiments. The Receiver Operating Characteristic curves show that our approach performs well in both detection probability and false alarm probability compared with the entropy-based approach. In addition, the mitigation effect is impressive that our approach can prevent most of the attacking traffic. At last, we evaluate the overhead of the system, including the detection delay and utilization of CPU, which is not excessive. Our anomaly detection approach is lightweight and effective.

I have studied the food habits of the Yi-dynasty that wrote in umsikbup as followings ; The stape foods are Bab (boiled cooked rice) 1, Myons (noodles) 4 and Mandu 5 kinds. The side dishes are Guk (soup) 3, Sinsollo 1, Jim 9, Jijim 1, Nooruemi 6, Sun 2, Po 3, Muchim 1, Jabans 3, Jockpyuns 2, Pyunyuk 1, Chae 2, and Kimchi 1 kinds. Thare are D'ock 22, Kwajung 46, Beverages 9 and alcohol are 4 kinds. There are many kinds of Dasikk of the Kwajung in the Umsikbup than no other cooking books. The seasonings are soybean sauce 5, honey 6, oil 4 and sesame seeds 3, ect. There are the description of food types in the seasonal variation and also there are the wisdom of life and avoiding food ; toxic meats, fishes, vegetables and fruits in the taboo food. There are most of Kwajung in the Chanhap (food packed in nest of boxes) in addition to beverages, D'ock, Mandu, decoration methods in the seasonal variation. There are many food making terms which are 163 kinds of prepared cooking term 27 kinds of cutting terms and 17 kinds of boiling terms. And 18 kinds of expression of taste can be seen in this book. There are 24 kinds of table were and cooking kitchen utensils, but many of them came to usefulness 12 kinds of measuring units are very non-scientific because that is not by weight but by bulk or volume.

A lot of studies of ship's economy are on the traditional fields such asreducing propulsion resistance, raising cargo handling rates and lessening building consts, but there are few researches on the merchant ship's economy concerning their deadweights and speeds according to shipping companies managerial cercumstances. Contrary to the contemporary trend that "the bigger, the better, if the cargo handling rate could increased sufficiently to hold down port time to that rate of smmaler vessels", this paper demonstrates the existence of certain limits in ship's size and speed according to the coditions of the freight rates, voyage distances, cargo handing rates, prices of fuel oil, interst rates etc. Fom the curves of criteria contour for various ship's deadweights and speeds which are depicted from the gird search method, one can get the costs and the yearly profit rates under the conditiions of large volume with long term contracts for the transportation of bulk cargoes. In estimating ship's transportation economy, the auther takes the position that the profit rate method is properer than the cost method, and introduces the calculation table of the voyage profit rate index. The use of the criteria contours will be of help to ship owners in determining the size and speed of the ship which will be built or purchased and serve in a certain trade route.
