This paper intends to suggest methods to design and implement a jQuery mobile based system in a future mobile webapp environment through a study on an N-Screen application in a mobile webapp. N-Screen is one of the representative services of cloud computing. It is promoted by the need of users to require universal functions for all devices. However, this situation is in conflict with the users' need to have the same experience and N-Screen cannot deal with these disparate services. Thus, this study intends to suggest a system analysis, structure of design, and a framework by implementing the N-Screen based movie reservation system in the jQuery mobile environment.

The neutron transmutation doping of silicon (NTD), as a method to produce a high quality semiconductor, utilizes the transmutation of a silicon element into phosphorus by neutron absorption in a silicon single crystal. In this paper, we present the design of a neutron screen for a 6' Si ingot irradiation in the NTD2 hole of HANARO. The goal of the design is to achieve an even flat axial distribution of the resistivity, or $Si^{30}(n,{\gamma})Si^{31}$ reaction rate, in the irradiated Si ingot. We used the MCNP4C code to simulate the neutron screen and to calculate the reaction rate distribution in the Si ingot. The fluctuations in the axial distribution were estimated to be within ${\pm}2.0%$ from the average for the final neutron screen design; thus, they satisfy the customers' requirement for uniform irradiation. On the other hand, we determined the optimal insertion depths of the Si ingots by varying the critical control rod position, which greatly affects the axial flux distribution.

This study has been conducted on touch screen interface design for mobile devices. It was intended to measure user’s satisfaction on one-handed thumb input mobile devices. Recent studies proposed the optimal touch button size, but it is inappropriate for mobile devices. Therefore, this study was focused on four touch key factors-width, height, the horizontal and vertical distance between touch keys-as independent variables. The ANOVA results showed that the user satisfaction of four touch key factors was significantly affected by the thumb input. It also apparent that the interactions between four factors were significant. As a result, the horizontal and vertical distance as well as the width and height affected the satisfaction of users. In addition, this study suggested satisfaction models which represent the top 30%, 50%, 70% of user satisfaction measurement. The results of this study could be used to design touch keys that are able to enhance the usability on touch screen based mobile devices.

In this paper, we propose a new design scheme of N-Screen emulator based on Cloud and then implement the emulator, in order to solve the critical point of N-Screen emulator based on Cloud. This method, without the emulator in the server, will be able to confirm the features of the emulator with a browser using Web Service. This means that the identical service is possible without regard to personal computer or mobile environment. Also, in order to emulating each different web browser engine of the various devices separately, we revise and manage the WebKit engine to be suitable to the characteristics of each device. In the previous design method, the number of emulators which can be shown in a monitor is restricted to 2 or 3. However, we show that the proposed design method can improve the performance of server to the extent that this method could operate more than 100 emulators per each server.

A fog screen consists of tiny water drops and the viewers see the image transmitted through the fog screen. In contrast to ordinary screens, the viewers can see the actors passing through the image on the fog screen on stage. In this paper, we describe methods to build a top-down fog screen where fog particles generated in top space fall by gravity forming a flat vertical screen. We use a fog generation technique in which fog particles come out of the water surface when ultrasound vibrators immersed in water tank vibrate. We describe how fog particles form a flat screen while coming out of the fog passage tunnel, by generating guiding winds beside the fog screen. This technique utilizes the principle that fog particles are generated on the surface of a water tank by an ultrasonic vibrator placed in a water tank. The technique of forming a guiding wind on both sides of the passage exit where the fog comes out and the design and manufacturing method of the fog screen generating device are described so that the generated fog group can maintain one plane.

This research is conducted on temporary street furniture, which is one of the significant factors that comprise the street landscape in modem cities. The primary purpose of this research is to present the guidance on direction of planning by examining the design and installation types of construction and screen fences usually established at construction sites for buildings, roads, parks and etc. The results are as follows: 1. The construction and screen fences at construction sites of urban areas used to be a mere tentative facility to prevent noise and safety accidents but have now incremented their roles to serve not only as a functional but also as an aesthetic element with a city view and harmonization with other elements taken into consideration. In particular, it is noticeable that, based on its unique feature of tentativeness, its role has developed to serve as street furniture that adds variability to the modem city. 2. There are two different types of screen fences: blackout type and transparent type. The transparent screen turns out to be used a lot at the construction site of building a skyscraper or differentiated building in downtown city area or in places where there are buildings of similar types and shapes located along the street in the vicinity of the construction site. 3. The actual cases of adopting the tentative construction and screen fences all at the same time as a single unit have been found in historically and culturally significant architectures with the screen design used to demonstrate the view after completion of construction or the characteristics of the architecture.

In recent days, a wide angle for slim depth in CRT(Cathode ray tube) is required to meet other rapidly growing slim FPD such as LCD and PDP. However, in making the CRT with a wide angle screen, problems, such as a difficulty in forming black matrix, and excessive formation of black matrix, can be occurred. In this work, we designed a new exposure filter systm to avoid these problems for a wide angle CRT. We changed the design concept from a filter-to-Panel method to a Panel-to-fater control method, which can control the Black Matrix to easily satisfy the user's request. This study suggests new filter design method for a wide angle CRT which has good screen qualify.

Game interface can be described as a method for communicating the information of the game, and with increase in complexity of the game and the role of interface also becomes complex. MMORPG of the present has a greater capacity than the RPG of the past, and because there are many information game users need to know such as uniqueness of the character, maturation system, beginning users who encounter MMORPG for the first time have difficulties in grasping the concept and the information of the game. Therefore, an interface design that assists theusers in understanding and adjusting to the game is needed. For the purpose of this dissertation, a study was conducted for an MMORPG screen layout design that enables quick understanding of game information for the inexperienced younger game users.
