The Center for Children's Foodservice Management periodically visited children's foodservice facilities for hygiene, safety and nutrition management, and the 'HSQ (Hygiene Safety Quotient) and NQ (Nutrition Quotient) Management Web & App Program' was developed and applied to improve the health, safety, and nutrition management status of children's foodservice facilities. The HSQ is a comprehensive hygiene and safety index consisting of six categories from the hygiene and safety checklist for children's foodservice facilities provided by the Ministry of Food and Drug Safety. The NQ is a nutrition index for foodservice facilities consisting of five categories from the nutrition checklist. First, this program can be used to efficiently understand the actual conditions of children's foodservice. Foodservice facilities are provided with the result report prepared by the center without restrictions on time or place. Second, it can be used as "a channel for comfortable communication with foodservice facilities". Foodservice facilities are provided with a route where questions and resolutions can be communicated to the center. Third, it is easy to compare and review the results of foodservice facilities by institution and number of visits while downloading the results data at the same time, as the result report is written based on hygiene, safety, and nutrition visits. Through such programs, it is believed that standardized work and integrated management will improve the work efficiency of the center's employees. It is also thought that these programs will promote healthier life-styles in children by establishing a safe food environment for children's foodservice.

In the preceding studies, an analysis of Saga Prefectural sightseeing information by a Self-Organizing Map (SOM) has been tried. And recent development on Information and Communication Technology (ICT) will help us to access any results via the mobile devices easily. This is why the mobile devices, e.g., smartphones and tablet computers, have an operating system installed, and we can improve their functions by downloading any applications on the Web. Then, in order to realize this basic idea, development of an application for the mobile devices is investigated through some computer simulations on the standard desktop PC in this paper. As a result, it is found that i) a developed feature map is useful to identify some candidate topics, ii) a touchscreen is suitable to show the feature map, and iii) arrangement of the feature map can be modified based on our interests. Then, it is concluded that the proposed idea seems to be applicable, even though further consideration is required to brush it up.

It is easy to access to the infinity information and programs, but it gives rise to the side effect. There are many side effects(ex. Hacking, Cracking, expose the personal information, etc). Nowadays, the computer virus raise the serious problems. The making program called Vaccine is work out a count measure. The Anti-Virus programs install on the client side computer and upgrade by downloading on the server's signature, the latest date, the program bound both of them is shown, but these programs have the defect that they have no remote control and no signature update because user's unconcern, This paper reported the research of existing virus infecting technology and the development of Web based Anti-Virus Scanner using the remote control on the internet server. Through this paper, I want to set up the counter measure for new virus easily, and to make more fast the vaccine for virus.

In this study, a cloud-based processing method using Agisoft Metashape, a commercial software, and Amazon web service, a cloud computing service, is introduced and evaluated to quickly generate high-precision 3D realistic data from large volume UAV images acquired in disaster sites. Compared with on-premises method using a local computer and cloud services provided by Agisoft and Pix4D, the processes of aerial triangulation, 3D point cloud and DSM generation, mesh and texture generation, ortho-mosaic image production recorded similar time duration. The cloud method required uploading and downloading time for large volume data, but it showed a clear advantage that in situ processing was practically possible. In both the on-premises and cloud methods, there is a difference in processing time depending on the performance of the CPU and GPU, but notso much asin a performance benchmark. However, it wasfound that a laptop computer equipped with a low-performance GPU takes too much time to apply to in situ processing.

This study attempts to derive an economic analysis model for journal evaluation and conducts a case analysis based on the model. Total costs are calculated and include administrative fees (such as binding, ordering, claiming, etc.) and subscription costs. The model quantifies qualitative benefits to users, a utility that combines usage data that has also been evaluated in the existing economic analysis models. The model is designed by the usage statistics of the web-based electronic journals, which have become important resources for research. Rankings are assigned based on how items are utilized to the goal of the mother institution. In the case study based on the KDI School Library, the highest ranking off was assigned to journals that patrons used for citation in their outputs. For journals that were used background information, i.e., full text downloading or browsing , each was assigned ranking of 2 and 1, respectively. According to the analysis, the top 20 journals provided 75% of the entire library utility, showing different user behaviors among different cohorts. We expect that the model makes it possible for librarians to measure the value of journals. It can provide a basic tool for journal selection, particularly in special libraries with custom needs.

Recently, as mobile internet usage has been increasing rapidly, malware attacks through user's web browsers has been spreading in a way of social engineering or drive-by downloading. Existing defense mechanism against drive-by download attack mainly focused on final download sites and distribution paths. However, detection and prevention of injection sites to inject malicious code into the comprised websites have not been fully investigated. In this paper, for the purpose of improving defense mechanisms against these malware downloads attacks, we focus on detecting the injection site which is the key source of malware downloads spreading. As a result, in addition to the current URL blacklist techniques, we proposed the enhanced method which adds features of detecting the injection site to prevent the malware spreading. We empirically show that the proposed method can effectively minimize malware infections by blocking the source of the infection spreading, compared to other approaches of the URL blacklisting that directly uses the drive-by browser exploits.
