The technology to locate an individual has enabled various services, its utilization has increased. There were constraints such as the use of separate expensive equipment or the installation of specific devices on a facility, with most of the location technology studies focusing on the accuracy of location verification. These constraints can result in accuracy within a few tens of centimeters, but they are not technology that can be applied to a user's location in real-time in daily life. Therefore, this paper aims to track the locations of smartphones only using the basic components of smartphones. Based on smartphone sensor data, localization accuracy that can be used for verification of the users' locations is aimed at. Accelerometers, Wifi radio maps, and GPS sensor information are utilized to implement it. In forging the radio map, signal maps were built at each vertex based on the graph data structure This approach reduces traditional map-building efforts at the offline phase. Accelerometer data were made to determine the user's moving status, and the collected sensor data were fused using particle filters. Experiments have shown that the average user's location error is about 3.7 meters, which makes it reasonable for providing location-based services in everyday life.

This study aimed to provide a basic information for managing the water quality of national and regional 1st rivers in Gyeongnam by analyzing the emerging hot spot patterns in BOD, T-P, and TOC, and by grouping the changing trends into clusters. The emerging hot spot analysis for each water quality item was implemented in ArcGIS Desktop with monthly water quality data from 96 water environmental monitoring stations in Gyeongnam, and then four patterns of water quality change were classified by the K-mean cluster analysis. As for BOD, persistent cold spot pattern covered about 42.9% of target rivers, and T-P concentration tended to be low or be getting lower at over 70% of target rivers. While, for TOC, about 70% of target rivers resulted in oscillating hot spots. In addition, the cluster analysis showed that the downstream of Nakdong river had the top priority in terms of water quality management because of the increasing concentration for all the three water quality.

The effect of improving awareness by educational programs for improving the quality of daily life of the disabled and safety depends on the type of disability and individual differences, as well as the difficulty in evaluating education achievement and satisfaction. However, more effective programs can be developed and provided if the factors affecting the effectiveness of education can be identified. Training as one of the factors affecting effectiveness involves motivation. This is thought to be an important factor for any object regardless of the type of disability. It is recognized that "By providing programs for the disabled to immerse themselves, they can be motivated to participate in education and expect greater effects on educational effects." Gamification is convincing enough for general learning. Furthermore, a feature of gamification is the use of the game's structure to achieve its goal, which acts on participants' motivation. Some use game packages such as analog games and digital games, but some include gamification of activities themselves. The use of gamification in education has different characteristics from the development of businesses. Therefore, in this paper, we reviewed the current status and challenges with the aim of promoting the use of gamification in life safety education for the disabled.

This study aimed to evaluate the necessity of updating current nutritional standards for school lunch programs in Korea. The study was performed both theoretically and practically considering the present physiques and nutrient intakes of school students. Theoretically, adequacy of types of nutrients and nutrient reference values were analyzed. Specifically, the adequacy of the types of nutrients were reviewed by applying the same selection procedures used in the 2007 revision of current standards in order to evaluate the necessity of updates. The nutrient reference values were compared with those in the U.S., Japan, and Taiwan in terms of setting year, basic data, and setting method. Practically, a focus group interview with six school nutrition teachers was conducted to investigate any operational difficulties in applying the current standards to school foodservices in Bucheon on October 1, 2015. As a result, nine types of nutrients were decided, which excluded protein and thiamin from the current ones. The nutrient reference values needed updating toward more adequate levels by reflecting more various and recent basic data considering daily nutrient intakes and the actual percentages of intakes from lunches of school students. The results showed that school nutrition teachers found it difficult to apply the current standards to school foodservices, especially as school level increased from elementary through middle to high schools mainly due to protein and calcium. Overall, the study results imply that the current nutritional standards for school lunch programs in Korea need updating to reflect the current physiques and actual nutrient intakes of school students.
