프랜차이즈 사업에 있어서 지역 정보 관리 시스템은 고객의 편의 제공 및 프랜차이즈의 수익 구조에 큰 영향을 준다. 프랜차이즈 사업에 있어서 중요한 점은 다양하게 존재하는 지역 정보들을 효과적으로 이용하는데 있다고 할 것이다. 현재 국내 사이트에서 구축되어 있는 지역 정보 관리 시스템은 분리된 해당 지역 정보만 제공하고 있는 실정이다. 즉, 통합된 체계의 정보 서비스가 되지 않고 있는 실정이다. 본 논문의 부 프로세스에서는 지역 사업을 하는 데 있어 필요로 하는 다양한 지역 정보를 데이터 베이스화하고 그에 따라 여러 가지 형태의 UI(User Interface)를 제공하고, 또한 상점에서 사용하는 사용자 프로그램의 개발과 상점의 특성을 파악하여 그에 맞는 컨텐츠를 제공한다. 본 논문에서는 이러한 부 프로세스의 개발의 기반 구조가 되는 관리자 시스템을 설계 및 구현한다. 즉, 지역 사업을 함에 있어 초기 데이터 구축 및 사업권 영역의 확장 및 관리라는 측면을 고려할 때 각 지역을 관리하게 될 MF(Master Franchise)와 F(Franchise)가 협력하여 현지의 현실감 있는 정보를 즉 시적으로 반영하며 구축해 나갈 수 있는 관리자 시스템을 개발한다.

본 논문에서는 사용자에게 편의성을 제공하며 기존 물물거래 시스템의 단점을 보완한 웹기반의 물물교환 시스템을 제안한다. 대부분 사람들이 중고거래나 필요 없는 물품에 대해 판매를 하는 목적은 자신에게 필요 없는 물건을 처리하고 필요한 물건을 구매하기 위해서이다. 이러한 사용자들의 관점에서 보았을 때, 필요한 물건을 얻기까지의 과정이 장시간 걸린다는 단점이 있으며, 사람들이 필요 없는 물건을 버려 낭비되고 과소비되는 경우도 있다. 이러한 문제를 해결해서 필요 없는 물건을 필요로 하는 사람과 물물교환을 하여 불필요한 소비를 줄이고 필요한 제품을 서로 쉽게 찾고 교환할 수 있도록 사용자에게 편의성을 제공하는 물물교환 시스템을 제안한다.

In this paper, we proposed a real-time education assistive technology system based on haptic display to improve education environment of total blindness people. The proposed system consist of a lecture and writing S/W for educator and a previously developed haptic display H/W for total blindness people. The one has the major function which is quickly and easily writing to the education data, that will be provided to total blindness people, through familiar UI, the other has the major function which print out the tactile information about the education data. The result of implementing system not only provides a similar result using existing braille instrument and printer, but shows that it is effective performance and functionality because it can print out the education data in real time.

The purpose of this study is to investigate the phenomenon of user's use of services, focusing on Skyscanner apps, and to suggest improvements to provide better user experience. The service described in this paper is complicated in booking ticket and deficient its usability at a certain age. As a result, three point of improvement is derived. Provide clear information and countermeasures. And make operating procedure be convenient to learn. It is significant that this study suggested ways to improve ticket reservation services through Skyscanner, a major online ticket reservation service. In the follow-up study, I expected that this study will help the various business models improve its system such as UI design, improvement of information structure, and Skyscanner for silver generation.

Design of the past focusing on molding and system is gradually changed into design focusing on users that reflects design philosophy considering users, and especially, the importance of User Experience Design that is to offer the best experience in using some products or services is realized. This study accessed design based on data having a low effect on function of wearable among changes that UX Design should consider in IoT generation. I think the data is diverse and many existing social commerce app, similar to the layout of the data in IoT devices based on the layout of the interface.Apps that data based model to analyze the layout. and the structure of the UX design were summarized.

Recently, NMEA2000 became the de facto standard of the communication protocol for the instrument level network in vessels, and it is anticipated that most of the vessels will be equipped with the sensors and actuators based on this protocol. The conventional serial communication specifications such as RS-232, RS-485, or even NMEA0183 are single-talker/multiple-listener and interconnection among multiple sensors and/or actuators usually results in a bundle of wires. On the other hand, NMEA2000 is a true bus type(multiple-talker/multiple-listener) protocol and theoretically up to 256 instruments can be hot-plugged. With the advent of the protocol, it is necessary to consider a new type of monitoring system for the instruments in vessels: In most traditional serial communication environments, a dedicated monitor or user interface was necessary for each sensor or actuator as it was simply not easy to collect data in a single place. With NMEA2000, the collection of various types of information is simple. An embedded system can be employed to combine, to arrange and to display informations from various types of devices. Assuming that the actuators and sensors on a vessel are interconnected by NMEA2000 standard, we devise a tentative interactive vessel monitoring system in which the following 4 kinds of informations are collected and delivered: the navigation, engine, weather and tanks informations.

This study analyzes patent trends by deriving sub-technical fields of Organic Light-Emitting Diodes (OLEDs) industry, and analyzing technology value, originality, and diversity for each sub-technical field. To collect patent data, a set of international patent classification(IPC) codes related to OLED technology was defined, and OLED-related patents applied from 2005 to 2017 were collected using a set of IPC codes. Then, a large number of collected patent documents were classified into 12 major technologies using the Latent Dirichlet Allocation(LDA) topic model and trends for each technology were investigated. Patents related to touch sensor, module, image processing, and circuit driving showed an increasing trend, but virtual reality and user interface recently decreased, and thin film transistor, fingerprint recognition, and optical film showed a continuous trend. To compare the technological value, the number of forward citations, originality, and diversity of patents included in each technology group were investigated. From the results, image processing, user interface(UI) and user experience(UX), module, and adhesive technology with high number of forward citations, originality and diversity showed relatively high technological value. The results provide useful information in the process of establishing a company's technology strategy.

A text-based communication system has been developed with a communication function on AIS and display and input function on ECDIS as a way to complement voice communication. It features no linguistic error and is not affected by VHF restrictions on use and noise. The text communication system is designed to use messages for clear intentions and further improves convenience of users by using various UI through software. It works without additional hardware installation and modification and can transmit a sentence by selecting only via Message Banner Interface without keyboard input and furthermore has a advantage to enhance processing speed through its own message coding and decoding. It is determined as the most useful alternative to reduce language limitations and recognition errors of the user and solve the problem of various voice communications on VHF. In addition, it will help to prevent collisions between ships with decrease in VHF use, accurate communication and request of cooperation based on text at heavy traffic areas.

The research for a 3-axial accelerometer sensor has increased dramatically in the fields of cellular phone, PDA, etc. In this paper, we develop a human walking detection algorithm using 3-axial accelerometer sensor and a user interface system to show the activity expenditure in real-time. To measure a walking number more correctly in a variety of walking activities including walking, walking in place, running, slow walking, we propose a new walking number detection algorithm using adaptive threshold value. In addition, we calculate the activity expenditure base on counted walking number and display calculated activity expenditure on UI in real-time. From the experimental results, we could obtain that the detection rate of proposal algorithm is higher than that of existing algorithm using a fixed threshold value about $5{\sim}10%$. Especially, it could be found out high detection rate in walking in place.

In this paper, calculation methods of resistance of the ship to be towed and towline tension are discussed. When the vessel is fallen into dead ship condition then appropriate towing force have to be estimated to move the vessel from accident place to safe area. In this research, resistance of the ship to be towed and the tow hawser were considered to estimate total towline tension. Polynomial interpolation method is also applied to estimate additional hydrodynamic resistance of towline. Finally, UI program to calculate the resistance and total towline tension is developed. The developed program based on the research results is effective and convenient to use.
