본 연구를 통해 e-business 웹사이트에서 사용자의 입력에 사용되는 어느 정도 표준화된 인터페이스 디자인들을 실험을 통해 비교하고 최적의 사용법을 알아내었다. 풀다운 메뉴, 텍스트 입력 창, 리스트, 라디오 버튼 등의 입력 디자인(도구)들이 실험에 사용되었으며 이들은 호텔 객실의 예약 웹사이트 시뮬레이션을 통해 비교되었다. 실험 결과 사용자의 입력 선택 사양이 4가지 이상인 경우 전문가에겐 텍스트 입력 창이 입력시간을 줄여주고 일반 사용자에게는 풀다운 메뉴가 사용성 측면에서 효율적임을 알 수 있었다. 단지 두 가지의 선택 사양이 존재할 경우엔 만족도, 유연성, 단순성을 고려했을 땐 리스트가 우수하며 사용 편의성 면에선 라디오 버튼이 최적의 인터페이스로 나타났다. 연구 결과를 사용자의 데이터 입력이 필요한 인터렉티브한 웹사이트의 디자인에 적용할 경우 경제적 효율과 사용성을 증대시킬 것이다.

It takes long time in numerical simulation because structural design for tire requires the nonlinear material property. Neural networks has been widely studied to engineering design to reduce numerical computation time. The numbers of hidden layer, hidden layer neuron and training data have been considered as the structural design variables of neural networks. In application of neural networks to optimize design, there are a few studies about arrangement method of input layer neurons. To investigate the effect of input layer neuron arrangement on neural networks, the variables of tire contour design and tension in bead area were assigned to inputs and output for neural networks respectively. Design variables arrangement in input layer were determined by main effect analysis. The number of hidden layer, the number of hidden layer neuron and the number of training data and so on have been considered as the structural design variables of neural networks.

Railway construction needs vast soil investigation for its infrastructure foundation designs along the planned railway path to identify the design parameters for stability and serviceability checks. The soil investigation data are usually classified and grouped to decide design input parameters per each construction section and budget estimates. Deterministic design method which most civil engineer and practitioner are familiar with has a clear limitation in construction/maintenance budget control, and occasionally produced overdesigned or unsafe design problems. Instead of using a batch type analysis with predetermined input parameters, data population collected from site soil investigation and design load condition can be statistically estimated for the mean and variance to present the feature of data distribution and optimized with a best fitting probability function. Probabilistic approach using entire feature of design input data enables to predict the worst, best and most probable cases based on identified ranges of soil and load data, which will help railway designer select construction method to save the time and cost. This paper introduces two Monte Carlo simulations actually applied on estimation of retaining wall external stability and long term settlement of organic soil in soil investigation area for a recent high speed railway project.

In a situation that building energy consumption is increasing worldwide, the research utilizing BIM technology to analyze building energy has been actively conducted. On the other hand, data input method of the building energy analysis has been still manually entered. This paper proposed a improved input method of required information for building energy analysis using the ECO2-OD program. As a result, although some required information of BIM based design software could be almost entered when it comes to general information and architectural sector, it has a problem to be handled in HVAC sector. Therefore, in the both of general and architectural sectors, the BIM information from the BIM-based design software could be directly used to automatically and systematically input the information. Future research should be studied the algorism and method in connection with data exchange to utilize input method of ECO2-OD from BIM data.

IoT devices frequently require input resources to communicate with various sensors or IoT platforms. IoT device wastes a lot of time as idle time or waiting time to check the data of the input resource and use the input resource. In addition, IoT devices use various input resources. We compares and analyzes input idle time and input waiting time generated from hardware serial input resource, software serial input resource, digital port input resource, and analog port input resource using Arduino widely used as IoT device. In order to design the IoT device framework, it is necessary to understand the characteristics of input resources and to design them to minimize unnecessary input idle time and input waiting time. The analog input wait time has a much larger input wait time than the digital input wait time, so it must be designed to receive analog information periodically at the appropriate timing. The characteristics of the input resources analyzed in this way help to design an efficient IoT device.

Mobile web applications are different from desktop web applications because of their small screen size and small user input devices. Therefore user interface designers have spent their effort and time to re-design the user interface of mobile web applications to meet these differences. In this paper, we introduce five user interface patterns for mobile web applications to reduce their effort and time. Two of them are for utilizing small screen size efficiently, and they are space overloading pattern and data filtering pattern. These patterns enable designers to reduce screen usage. The other three patterns - data suggestion pattern, input reuse pattern, and incremental data input pattern - are for helping users' data input on mobile devices. These three patterns enable users to reduce direct data input. Our work will help user interface designers develop mobile web interface to utilize screen space efficiently and get data with less errors and less efforts from users.

In this paper, we introduce a new design of fuzzy neural networks using input-output data information of target system. The proposed fuzzy neural networks is constructed by input-output data information and used the center of data distance by HCM clustering to obtain the characteristics of data. A membership function is defined by HCM clustering and is applied input-output dat included each rule to conclusion polynomial functions. We use triangular membership functions and simplified fuzzy inference, linear fuzzy inference, and modified quadratic fuzzy inference in conclusion. In the networks learning, back propagation algorithm of network is used to update the parameters of the network. The proposed model is evaluated with benchmark data.

프랙탈 영상압축의 고속처리를 위한 일차원 VLSI 어레이를 설계하였다. 기존의 제안된 일차원 VLSI 어레이에서 중첩되는 이웃의 정의역블럭의 데이터들을 재사용하므로서 전체 연산에 필요한 데이터의 총입력 횟수를 감소시키고, 이로 인한 전체 처리시간을 줄였다. 어레이로 입력되는 데이터의존관계를 고려하여, 입력순서가 적절히 조정되었으며, 이에 따라 처리요소들을 설계하였다. 몇몇 처리요소에는 데이터의 저장 및 경로설정을 위한 레지스터와 멀티플렉서들이 추가되었다. 따라서 영상의 크기가 N이고 블럭의 크기가 B인 경우, 이 설계는 적은 하드웨어를 추가하여 기존의 어레이보다 처리속도가 (N-4B)/4(N-B)배 향상되었다.

2차원 평면 입력을 통한 모델링에서는 입력 값을 3차원 데이타로 바꾸기 위한 기능과 메뉴들이 필요하지만 가상공간 디자인을 위한 3차원 입력 시스템은 입력 값을 곧바로 3차원 데이타로 변환될 수 있다. 하지만 3차원 입력시스템에서 효율적인 곡면 모델링 방법, 특히 곡면 변형 방법은 제안되지 않고 있다. 본 논문에서는 기존의 변형방법이 3차원 입력시스템에서 적용되었을 때 발생할 수 있는 문제점을 제시한다. 그리고 디자이너가 접근하기 쉬운 목표곡선을 이용한 변형을 제안한다. 이와 같은 3차원 목표곡선을 이용한 변형을 통해 디자이너가 보다 쉽게 3차원 입력시스템에 접근하여 가상공간 스케칭 및 디자인을 구현할 수 있다.
