The study on the development of local food inventory management system is presented. In the case of a current distribution system for small and big stores, the person in charge must be able to check the status right away and be able to fill the display, whenever the amount of displayed products is reduced. However, we have developed the system which alerts suppliers to fill the product, when the weight of the display goes below a certain level from the initial weight of the filled-display using electronic scale for measuring the weight to mobile. With the system, it is able to operate efficiently by real-time sharing of filling-time on mobile. The proposed system can provide customers with fresh products through reduction in labor force and the day of harvest and sale of local food stores, and simplify the distribution channel.
웹 페이지 비교통합 기반의 정보 수집 시스템 설계 및 개발에 대한 연구

Recently, the quantity of information that is accessible from the Internet is being dramatically increased. Searching the Web for useful information has therefore become increasingly difficult. Thus, much research has been done on web robots which perform internet information filtering based on user interest. If a web site which users want to visit is found, its content is searched by following the searching list or Web sites links in order. This search process takes a long time according as the number of page or site increases so that its performance need to be improved. In order to minimize unnecessary search with web robots, this paper proposes an efficient information collection system based on compare and merge method. In the proposed system, a web robot initially collects information from web sites which users register. From the next visit to the web sites, the web robot compares what it collected with what the web sites have currently. If they are different, the web robot updates what it collected. Only updated web page information is classified according to subject and provided to users so that users can access the updated information quickly.
자동차 연료 펌프용 BLDC 모터의 센서리스 기동 및 연료 압력 제어
장진욱,배진한,윤덕용 대한전기학회 2012 대한전기학회 학술대회 논문집 Vol.2012 No.4
자동차의 연비와 배출 가스에 대한 규제가 강화되면서 연료의 효율을 개선하는 것은 물론이고 자동차에 사용되는 모터에 대한 효율 향상이 요구되고 있다. 본 논문에서는 자동차 연비를 개선하기 위하여 연료펌프의 압력을 제어하고, 그에 사용되는 모터를 효율이 높은 BLDC 모터로 선정하여 센서리스 방식으로 운전하는 방법에 대하여 연구하였다. BLDC 모터의 센서리스 기동 특성을 개선하기 위하여 테스트 전압 펄스를 인가한 후 전류 응답을 측정하는 방법으로 초기 회전자의 위치를 검출하였고, 이로부터 강제 구동 방식으로 모터를 가속하여 센서리스 모드에 진입한다. 자동차 연료 펌프의 유량을 제어하는 방법으로는 PI 제어기를 사용하여 BLDC의 속도 제어를 수행함으로써 연료의 압력이 ECU로부터 지령받은 목표 연료 압력을 추종하도록 한다.

In this paper, we proposed an automatic TOD synchronization and verification method for improving the performance of air-to-ground radio(hereafter SATURN) of legacy aircraft. In order to automatically synchronize TOD with SATURN radio, it is proposed to modify the GPS antenna installed in the existing aircraft according to the minimum operating performance standard. In addition, test methods and results are presented to verify the TOD information generation capability before and after the GPS antenna modifying. It is expected that the automatic TOD synchronization method proposed in this paper can be applied to the SATURN performance improvement design.
Improvement of the Automobile Control Software Testing Process Using a Test Maturity Model
장진욱 한국정보처리학회 2018 Journal of information processing systems Vol.14 No.3
The problem surrounding methods of implementing the software testing process has come under thespotlight in recent times. However, as compliance with the software testing process does not necessarily bringwith it immediate economic benefits, IT companies need to pursue more aggressive efforts to improve theprocess, and the software industry needs to makes every effort to improve the software testing process byevaluating the Test Maturity Model integration (TMMi). Furthermore, as the software test process is only atthe initial level, high-quality software cannot be guaranteed. This paper applies TMMi model to Automobilecontrol software testing process, including test policy and strategy, test planning, test monitoring and control,test design and execution, and test environment goal. The results suggest improvement of the automobilecontrol software testing process based on Test maturity model. As a result, this study suggest ITorganization’s test process improve method.

Cheongnyangni station, one of the oldest train stations in Korea, has undergone dynamic transformation beginning from the Japanese colonial period, to the post-war period, and finally through modern times. Although the physical form has significantly changed through its history, it always has served as a public facility. Nonetheless, Cheongnyangni station always had symbolic characteristics and hidden purpose beyond the station itself. Its symbolic metaphor can be understood as exerting authority during the Japanese colonial period, as a showcase of US hegemony in the post-war period, and as a tool of urban development in modern times. In a word, various socio-cultural aspects, such as symbolic characteristics or hidden purpose have been effected on architectural change, including form, material and program rather then optimizing convenience of user group. Since the 10 years during which the train station as a building type was used as a tool of urban development, Seoul Metropolitan government continues to propose numerous train stations in the form of transit centers to tackle over-crowded urban problems related to mobility. At this moment, a sophisticated approach is required to develop a new type of train station in terms of socio-cultural aspects. By tracing back to the historical change of the train station with socio-cultural background, this research can be a foundation for future train stations that are, actively linked with society, culture, and context through the integrated pedestrian networks, bus transportation systems, and interfaces with automobiles.
