  • In mobile browser two mental models coexist; one for mobile users and the other for PC users. In this research shows that users apply these two mental models simultaneously while they use mobile browsers. However cases where these two mental models conflict with each other, rapid deterioration of usability of the UX based on the mobile user's mental model was evident. Also usability of mobile user interfaces for use cases like "View Mode" or "Copy and Send Mode" were also poor, and the research shows that these "Modes" could be substituted by gesture interaction with which users were already familiar.

  • The acoustic property of reactive type single expansion chamber can be analyzed by traditional plane wave theory. This theory can be applied in low frequency range and has good performance. But this theory can't include higher order modes, therefore another method is essential to analyze acoustic filter in high frequency range. Many researcher suggested the method that can concern higher order modes, and their methods are using mode matching technique. But there is no method that can be applied to the analysis of single expansion chamber with arbitrary inlet/outlet duct position and numbers of higher order modes of inlet/outlet duct and middle chamber. In this paper, the method which can analyze single expansion chamber with arbitrary inlet/outlet duct position and numbers of higher order modes of inlet/outlet duct and middle chamber using fundamental mode matching technique, was suggested and the predictions by this method was compared with those by the finite element method, and the influence of inlet/outlet location to acoustic performance of single expansion chamber is investigated and explained by higher order mode effects.

  • Smartphones have been widely used for various purposes and stay connected with people at all times. However, the use of such touchscreen devices can be physically restricted depending on users' context where only one hand is available to interact with the device. Even major smartphone manufacturers (e.g., Apple, Samsung) offer one handed mode, they still lack functions in the third-party applications, and the process is also complicated. We propose OverIT, a system that enables users to customize interfaces by adding new buttons on an interactive overlay which can be positioned anywhere on the touchscreen where each button serves the same functionality as an existing one. It is designed to support users to map a certain button event freely and easily to a newly created button by performing a demonstration of a button tap. We expect our system to improve the overall user experience of one-handed interaction with touchscreen devices.

  • 본 논문에서는 2.5 Gb/s의 입력 데이터율을 가지는 버스트 모드(Burst-mode) 클럭 데이터 복원기(CDR: Clock and Data Recovery)를 제안한다. 제안된 버스트 모드 CDR에서는 입력 데이터율과 클럭 복원기의 개폐 전압제어발진기(GVCO: Gated Voltage Controlled Oscillator) 출력 주파수간의 불일치를 제거하기 위하여 디지털 주파수 보정 기법이 적용되었고, 또한 입력 데이터로 인하여 발생하는 지터(Jitter)를 감소시키기 위하여 지터 제거 기법이 적용되었다. 제안된 버스트 모드 CDR은 0.11 ${\mu}m$ CMOS 공정을 사용하여 설계되었고 루프필터를 제외한 회로 설계 면적은 0.125 $mm^2$이며 전력 소모량은 94.5 mW이다. 포스트 레이아웃 시뮬레이션 결과, 제안된 회로를 통하여 복원된 데이터는 0.1 UI의 입력 지터 인가 시 14 ps의 peak-to-peak 지터를 가지며 최대 허용 CID(Consecutive Identical Digit)는 입력 데이터 지터가 없을 경우 2976 bits를 가진다.

  • Bioventing efficiency was compared in a continuous and an intermittent(6hr injection and 6hr rest) air injection mode. Two lab-scale columns which packed with 5kg of soil artificially contaminated by diesel oil were operated. The columns were maintained at the $25^{\circ}C{\pm}2.5$ in order to minimize the effect of exterior temperature variation. The flow rate of air injection mode were maintained constantly at the flow rate of 10ml/min. The moisture of the columns was stably maintained at $60{\sim}80%$ of field capacity. The nutrient compounds were added to make C : N : P ratio as 100 : 10 : 1. The continuous and intermittent injection modes showed 67.56% and 69.63%reduction of initial TPH concentration during 90 days, respectively. The loss of diesel oil by volatilization in the continuous and intermittent injection modes were about 5% and 1%, respectively.

  • Distributed generation (DG) in the future will play an important role in the electricity supply systems, in wich can provide DG capacity from a few hundred kW to tens of MW. However, it is connected to the local power grid, DG will have certain influence on the power quality of the power grid. One of the most significant effects is that they will change the configuration of the local power grid as well as affecting the operation mode of the grid. This paper presents a method of finding the optimal open loop, analyzing and selecting the appropriate mode of operation to reduce power losses of power distribution networks that includes DG.

  • A hair-pin shaped microstrip-line resonator and a dielectric resonator for injection-locked oscillators have been designed and fabricated for the comparative studying of their characteristics. In general, a commonly used dielectric resonator shows lower phase noise value than hair-pin resonator in the free-running mode. In the injection-locked mode, however, a hair-pin resonator is superior to the dielectric resonator; the wider tuning range, the 22% improved locking bandwidth, the lower noise effect, the short term stability, and the higher power level. The planar structure of a hair-pin shaped microstrip-line resonator will be easily applied to monolithic microwave integrated circuits.
