In this paper, we investigated the current limiting characteristics due to the application location of the superconducting fault current limiter (SFCL) such as the feeder, the bus, the secondary side of transformer in a power distribution system. In addition, the quench and the recovery characteristics of the SFCL installed in each location of the power distribution system were compared each other. Through the analysis, in case that the SFCL was applied into the feeder line, its current limiting and voltage-drop compensating characteristics were confirmed to be the more effective. On the other hand, the power burden of the SFCL was increased higher compared to the SFCL'S other application location.

A lot of PSC railway bridges have been constructed in countries and, they are considered as cost-effective and less maintenance-demanded structures. However, recently several collapse of PSC bridges happened in Europe show that PSC bridges have some serious maintenance problems related to tendon corrosion and wire fractures. Furthermore, any reliable NDT method is not presented until recently. In this paper, AE techniques are investigated for detection of wire fractures in PSC beam. Using long-term monitoring AE techniques, two acoustic signals of wire fractures in a PSC beam are obtained. These data are compared to other noise signals. Based on the test results, the characteristics of the AE signals are classified and wire fracture signals are figured out among the other AE signals. As a result, AE techniques are certainly exposed to tendon fracture sound, and application of AE techniques are better than any other non-destructive method.

최근 휴대용 기기들이 대중화되어 한 사람이 하나 이상의 휴대용 기기를 소지하고 있고 스마트폰 활용도 또한 늘어나는 추세이다. 스마트폰이 많이 보급됨에 따라 폭발적으로 스마트폰의 애플리케이션 활용이 늘어나고 있다. 현재의 애플리케이션 스토어는 플랫폼별로 애플리케이션을 개발해줘야 하는 종속적인 면이 있다. 앱스토어는 크게 애플의 앱스토어와 구글의 안드로이드 마켓으로 양분되어 있고 각 플랫폼에 맞춰 애플리케이션이 개발되어야 한다. 각각의 플랫폼에 맞춰서 애플리케이션을 개발하면 개발 비용은 2배에 근접하고 다른 소규모 플랫폼(Ex 바다)들은 애플리케이션 개발자들을 모아야만 자신들의 플랫폼에 맞는 애플리케이션이 나오는 단점이 있다. 이러한 플랫폼에 맞춰서 개발된 네이티브 애플리케이션의 범용성에 대한 해결책과 모바일에서의 다양한 요구사항을 수용하기 위해 웹 애플리케이션이 각광받고 있다. 웹 애플리케이션은 플랫폼에 종속되지 않고 어느 휴대용 기기에서도 동작하기 때문에 각 플랫폼별로 개발하지 않아도 된다는 장점이 있다. 따라서 웹 애플리케이션 스토어끼리의 연동 프로토콜을 통해 애플리케이션을 연동하여 어느 웹 애플리케이션 스토어에서도 볼 수 있고 특정 플랫폼에 구애받지 않는 거대한 시장이 생겨날 수 있다. 하지만 아직 웹 애플리케이션 스토어라는 표준이 없고 존재하는 웹 애플리케이션 스토어가 없다. 이를 위해 본 논문에서는 연동에 관한 프로토콜을 제안하고 구현을 통해 기존의 애플리케이션 스토어의 단점을 보완할 수 있는 방법을 제시한다.

Purpose: This study analyzes the effects of variables affecting e-satisfaction and e-loyalty in e-commerce. Research design, data, and methodology: A survey was conducted to 384 Indonesia online shopping mobile application users. The questionnaire construct was designed based on several independent variables, such as application attractiveness, application functionality, and customer service on e-satisfaction and e-loyalty. E-satisfaction was positioned as an intervening variable to determine the effect on e-loyalty. Results: Application attractiveness, application functionality, and customer service shown positive effect on e-satisfaction in online shopping mobile application. At the same time, e-satisfaction also affected e-loyalty significantly as referred in previous studies. However, application attractiveness, while showed positive effect on e-satisfaction, in contrary with previous study does not showed very significant effect. Conclusion: Application functionality significantly influences users satisfaction compared to application attractiveness. E-satisfaction mediates as a factor between visual design, information access, and transaction in online shopping mobile application, which stimulates user loyalty. The study findings' can be a reference for companies to create and maintain users' satisfaction and loyalty via different aspects of mobile application. Further research should be conducted on other field of study as the industry has different aspects that affects user loyalty.

This paper traces the process of constructing a new one-dimensional chaotic map, and will provide a simple application in color image encryption. The use of Sarkovskii's theorem will make it possible to determine the existence of chaos and restrict all conditions to ensure the existence of this new sequence. In addition, the sensitivity to initial conditions will be proved by Lyapunov's index value. Similarly, the performance of this new chaotic map will be illustrated graphically and compared with other chaotic maps most commonly used in cryptography. Finally, a humble color image encryption application will show the power of this new chaotic map.

This experiment was undertaken to study effect of fall Fertitizarion on spring regrowth of Korean lawngrass( Zoysia japonica Steud ) Results obtained are summarized as follows : 1. late fall fertilization stimulated the spring regrowth of Korean lawngrass. hut early spring application showed little effect on that 2. The yield of clippings on May 21 was obviously greater in late fertilization plots(treatment C, D and E) than other plots(treatment A, B and control, but there was no significant difference in clipping yields of C, D and F treatment. 3. Both nitrogen and reducing sugar contents of runner fell down in spring. It was suggested thatthese constituents be translocated from runner to other parts during the budding period. 4. The nitrogen content of runner was obviously mote in the plot of late fall fertilization. In contrast to nitrogen, no obvious difference was found in reducing sugar content of runner of seven application date. It was suggested that the roots of plant be still able to absorb to absorb nitrogen under dormancy. .5.From these results. late fall fertilization enhances the development of Korean lawngrass in the following spring. But early spring application shows little effect on spring regrowth.
