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.

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.

Corundum single crystals were grown in cryolite flux with the composition of Na3AlF6:Al2O3=80:20 wt%. This mixture was melted at 115$0^{\circ}C$, followed by slow cooling at a rate of 2$^{\circ}C$/hr to 96$0^{\circ}C$. And by adding of La2O3 to the flux, the change of crystal forms were observed. Crystal forms of corundum grown in cryolite flux had the habits of hexagonal plate which consist of well developed {0001} face and small {101} face. As La2O3 was added and its content was increased, {223} and {110} faces were developed, and crystal habits of equidimensional forms changed into hexagonal prism form. In a charge of 8 mole% B2O3, Al2O3:La2O3=15:1, transparent corundum single crystals of equent form were grown. As the content of B2O3 was increased, twineed crystals which have twin law of 2-fold parallel to [0001], and composition plane of (110) were grown.

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.
