In this paper, we propose an automatic order system for restaurant customers, which utilizes QR code and provides multilingual menu and currency conversion. The system consists of 2 main parts : application for customers, web and application for restaurant managers/owners. The main functions of the system are described with captured screens in this paper. Customers use the smart phone application and QR code tag attached each table to make orders. The multilingual menu and various currency feature help the foreign customers to make orders easily. The orders made by customers are automatically displayed in the smart phone or tablet installed in the cashier count and kitchen. The orders can be managed using web based system. 본 논문에서는 최근 빠르게 도입되는 무인 주문 서비스를 적용하여 다양한 식당과 국내외 소비자를 대상으로 개발된 QR 코드를 이용한 <다국어 간편 주문 시스템>에 대해 설명한다. 개발된 시스템 ‘QRans Order’는 식당 고객용 스마트폰 어플리케이션과 식당 운영자용 관리자 웹 및 스마트폰 어플리케이션으로 구성되어 있다. 본 논문에서는 개발된 시스템의 주요 기능을 화면 구성과 함께 설명한다. 시스템 구현 결과, 식당 고객용 스마트폰 어플 리케이션은 테이블마다 마련된 QR 코드를 이용하기 때문에 직원을 부르지 않더라도 앉은 자리에서 간편하게 음식을 주문할 수 있다. 또한, 다국어 기능을 통해 외국인 고객들도 간편하게 메뉴를 보며 주문할 수 있으며 선택한 언어에 따라 환산된 가격 정보도 알 수 있다. 식당 운영자용 관리자 웹 및 어플리케이션에서는 주문이 들어올 때마다 즉각적으로 주문 내역을 확인할 수 있으며, 식당 정보 및 메뉴 관리, 매출 관리 등의 업무를 체계적으로 관리할 수 있다.

맹주양,한찬수 순천향대학교 1994 논문집 Vol.17 No.3

Five 3-phenyl-l-(2-furyl)propenone derivatives were prepared by the condensation reactions of acetylfuran with benzaldehyde derivatives. The rate constants for hydrolysis of 3-phenyl-l-(2-furyl) propenone derivatives were determined at various pH in 50% MeOH-water mixed solvents at 25℃ (u=0. 1 NaCl). From the observed rate constants, rate equations, isosbestic points, general base effect, substituent effect and product analysis, the reasonable mechanism was proposed. From the results, the reaction mechanism was proposed 1,4-Michael type addition reaction of a, b-unsaturated ketones with water. Below pH8.0, water added to the carbon-carbon double bond of 3-phenyl-l-(2-furyl) propenone derivatives. At pH 8.0-12.0, water molecules and hydroxide ion added competitively to carbon-carbon double bond of 3-phenyl-l-(2-furyl) propenone. Above pH12, hydroxde ion added to the carbon-carbon double bond of 3-phenyl-l-(2-furyl) propenone.

Epidemiological studies suggest that 30-50% of patients diagnosed with symptomatic congestive heart failure(CHF) have electrocardiographic evidence of a major intraventricular conduction delay, which may worsen left ventricular systolic and diastolic dysfunction through asynchronous ventricular contraction and paradoxical interventricular septal wall motion. Biventricular pacing is an emerging therapy allowing simultaneous electrical stimulation of the both ventricles with an implantable pacing system and it improves hemodynamics and well-being of patient by reducing ventricular asynchrony. Recently, we underwent biventricular DDD pacemaker implantation in a patient with CHF and Left bundle branch block and was significantly improved exercise tolerance and quality of life in that patient.

In this study, nine reinforced concrete infilled frames involved bare frames were tested during vertical and cyclic loads simultaneously. This test programs were carried to investigate the horizontal strength and the crack propagation in variance with hoop reinforcement ratio. All specimens were modeling in one-third scale size. In this experimental program structural performance of reinforced concrete shear wall were focus at connection types. Based on the test results, the following conclusions are made. (1) In fully rigid frame, increasing the ratio of hoop bar 2∼3 times on the basis of its ratio of in column(p??=0.196%). The horizontal strength of specimen did not varied, but the increased ductility of specimens were showed greatly at the final failure. (2) In the boundary column menber of reinforced concrete shear wall, increasing the ratio of hoop bar in two or three times, in the fully babel type, the shear and horizontal strength of specimens were increased 1.1-1.2 times than that of fully rigid frame. And infilled shear wall specimen were increased 1.17-1.27 times than that. (3) Fully rigid babel type shear wall specimens were increased 5.7∼8.0 times, and infilled shear wall specimens were increased about 4.0∼5.6 times in comparision with the full rigid frame.

Since the fuzzy inference algorithm wastes a lot of time, the look-up table was used in order to reduce the wasted time. This algorithm has the disadvantage that shows the side vibration at the target point. In this paper, we proposed that the method of reducing the speed of convergence and vibration at the target point on calculating the membership degree about input value without a look-up table was proposed. And its effectiveness in the inverted pendulum was acquired. It is possible to accurately control the inverted pendulum by using the proposed method that controls the quantized level for speed of convergence, and changes the number of rules for reducing the vibration at the target point. In the case of a wide quantized level, the speed of convergence was better than at a narrow quantized level. And at the target point the vibration was irregular with a small number of rules. But by increasing the number of rules the vibration was constant and fixed.

As a result of the recent flood crisis, calculation of effective design flood becomes important. The main objective of this study is to simulate design flood of the Seongjoo watershed using GIS(Geographical Information System) and HEC-HMS. Parameters of Seongjoo watershed were extracted by using GIS technique. Time of concentration was estimated Kraven(1∼4 sub-basin), Riziha(5, 6 sub-basin) formulas. The temporal pattern or hyetograph of rainfall can make a significant effect on the peak value and shape of hydrograph, and Yen-Chow, Huff, Keifer-Chu method were applied for this study. This rainfall distribution type could be considered to calculate designed flood. In case that sub-basin was divided, design flood tend to be calculated smaller by storage and retardation of river channel routing. From the result of the runoff rate of 3rd in Huff's 4th quantiles method, the peak runoff rate was magnified by the constant rate when duration increased. 15hr was suggested as an optimal duration time of Seongjoo watershed.

Agents are a powerful abstraction through which users may interact with a complex data universe by delegating tasks involving objects or events of interest. Digital libraries are one of the many application areas where agent technologies are used. In these architectures, digital libraries are seen as a decentralized collection of interacting self-interested agents where an agent represents the knowledge and interests of an individual user. This paper describes intelligent agents based architectures for digital libraries and suggest an intelligent agents based virtual university, a limited version of digital library.

자동화요구분석 시스템의 설계에 관한 연구 : 요구명세서 오류검증을 중심으로 Centered on Verifying Errors in Requirement Specification

박찬란,이성주 조선대학교 기초과학연구소 1989 自然科學硏究 Vol.12 No.1

The quality of softwares depends upon the validity how exactly they perform in accordance to their purpose and how maintainable they are. If there is an error in requirement specification describing user requirement or if it is not correct, the result that the software developed by this requirement specification produce is different from user requirement, and it is not to be trusted. Therefore, the analysis stage for producing a correct requirement specification is of more importance in the software life cycle. Many kinds of requirement analysis tools have been developed in order to improve the above defects and Structured Analysis Methodology is typical of them. The Structured Analysis Methodology is useful for users to understand easily because it describes the items of user requirement as a graphic model and a way of partition, but it has such defects that it lacks in the ability of system modeling of the user's requirement contents which are fragmentary and descriptive as a formalized form and it is impossible for it to verify errors automatically. In this thesis, I have studied of the Requirement Analysis System, and have designed the system to verify automatically errors of requirement specification in order to improve theses defects.

교수-학습과정의 기호학적 탐구

이찬주,박범석 동국대학교 교육연구원 2005 교육문제연구 Vol.16 No.-

기호학적 입장에서의 의미 전달은 기호에 의한 의미의 교환이라 할 수 있다. 기호가 언어보다 폭넓은 인간 의식의 이해를 반영한다는 점에서, 인위적으로 설정된 상징체계 이외에 자연스러운 상황이나 이미지 자체도 하나의 기호적 의미의 범주로 해석될 수 있다. 교사와 학생의 가르치고 배우는 활동 역시 지식의 일방적인 전수가 아니라, 다양한 기호들이 상호소통함으로써 의미전달과 창출을 끊임없이 경험하는 해석적 활동이 된다. 교육활동 그 자체가 일종의 해석적 활동이기 때문에 이들 사이에 어떤 형태의 의미교환이 이루어지는가를 규명하기 위해서는 교수-학습의 기호적 역동관계를 이해하는 일이 선행되어야 한다. 따라서 교사와 학생 사이의 의미전달과 획득의 측면을 인간의 기호적 인식의 특성을 통해 밝히는 것은, 기존의 텍스트의 성격 이해를 중심으로한 해석적 연구에서 한 걸음 더 나아가 의미화 과정에서 일어나는 교육 주체들의 인식과정을 설명하는 하나의 계기가 될 것이다. The purpose of this study is to investigate the meaning of teaching-learning process in the view of Semiology. In Semiology, education is the enlarging process of meaning between teacher and students in the classroom as a field of signs. It is the hermeneutics activities to student which learn from the teacher and the text. It means students don't take the meanings not just direct way but translating way as their own meaning structures. In the same way, we can say that even teachers don't convey the meaning to students. They translate the meanings for students representing their own understanding structures. It can be said that the teaching and learning process is the relationships of hermeneutic cycle. In Semiotic view points, educational texts is not just the tools of information transmission. We can recognize the educational texts is the dynamic products from the meaningful actions between the two educational agents. These kinds of Semiotic views can give the new visions to clarify the educational communication between teachers and students in the classroom.
