This study was conducted to develop software which provides automatic site-specific field data acquisition, data processing, data mapping and management for precision agriculture. The developed software supports acquisition and processing of both digital and analog data streams. The architecture was object-oriented and each component in the architecture was developed as a separate class. In precision agriculture research, the laborious task of manual ground-truth data collection will be avoided using the developed software. In addition, gathering high-density data eliminates the need for interpolation of values for un-sampled areas. This software shows good potential for expansion and compatibility for variable-rate-application (VRA). The FIM (Field Information Management) computer program provides the user with an easy-to-follow process for field information management for precision agriculture.

Today's computer systems are widely integrated with CPU and GPU to achieve considerable performance, but energy consumption of such system directly affects operational cost, maintainability and environmental problem, which has been aroused wide concern by researchers, computer architects, and developers. To cope with energy problem, we propose a task-scheduling framework to reduce energy under performance constraint by rationally allocating the tasks across the CPU and GPU. The framework first collects the estimated energy consumption of programs and performance information. Next, we use above information to formalize the scheduling problem as the 0-1 knapsack problem. Then, we elaborate our experiment on typical platform to verify proposed scheduling framework. The experimental results show that our proposed algorithm saves 14.97% energy compared with that of the time-oriented policy and yields 37.23% performance improvement than that of energy-oriented scheme on average.

In this paper, a controller is designed for efficient controlling of video data with object-oriented feature. The need of controlling video data in an object unit is on the rise for the reason of rapidly growing demand for high-quality video services. We propose a programmable architecture with stack buffers which can minimize a scheduling overhead by having separate buffes for genral data and return addresses. The buffers are veyr useful for move and copy operations for multitasking and task switching. The controller offers extended instructions that process several data types including 32bit integrer type. Operation speed of the controller is from 77MHz to 44MHz.

The present study was initiated under the hypotheses that value orientation of wives is closely related to their decision making style in home management and that family life satisfaction of wives varies according to their decision making style. To test the hypotheses the following procedures were undertaken; (1) developing measurement instruments for value orientation, decision making style, and family life satisfaction; (2) finding value orientation of wives, their decision making style, and their family life satisfaction by applying the measurement instruments; (3) finding the variables highly affecting value orientation, decision making style and family life satisfaction ; and (4) finding the causal mechanism among value orientation, decision making style, and family life satisfaction. In conclusion , preferences of wives for humanism in value orientation were expected to lead decision making style to person -oriented rater than task-oriented style and , furthermore, to result in higher family life satisfaction.

In this paper, we present a technique to extract the title areas from book cover images. A typical book cover image may contain text, pictures, diagrams as well as complex and irregular background. In addition, the high variability of character features such as thickness, font, position, background and tilt of the text also makes the text extraction task more complicated. Therefore, we propose a two steps efficient method that uses Histogram of Oriented Gradients and color information to find the title areas. Firstly, text localization is carried out to find the title candidates. Finally, refinement process is performed to find the sufficient components of title areas. To obtain the best result, we also use other constraints about the size, ratio between the length and width of the title. We achieve encouraging results of extracted title regions from book cover images which prove the advantages and efficiency of the proposed method.

This study was conducted to compare team creativity and creative problem solving styles between heterogeneous and homogeneous teams. Team composition was based on the levels of openness and extraversion. The results indicated that heterogeneous teams showed higher team creativity scores than homogeneous teams. Frequency distributions of creative problem solving styles indicated that heterogeneous team members preferred developer, external, and task-oriented styles. Homogeneous team members preferred explorer and person-oriented styles. Finally, limitations of this study and suggestions for future studies were discussed.

The irrigation facilities are managed systematically and a facility is independent at the view of shape and function. The design of the irrigation facility is the formulated process with independent objectives. So its process is accordance to object-oriented concept. The design of irrigation facilities is classified into several steps. In these steps, the design data is made and the various problems are solved and consolidated with analysis and decision. In order to achieve our goal of constructing an efficient integrated design system, the results from the design should be able to be systematically connected and re-used. In the study, the design task of irrigation facility, the integrated design system for (IDSAF) is to be developed using the object-oriented methods, and then its applicability will be examined.

This paper deals with effectiveness of Object-Oriented Modeling and Design(OOMD) through GroupSystems V which is a typical groupware or group decision support system(GDSS) to aid group work. Objective and subjective evaluations between traditional non-GDSS face-to-face group and GDSS-supported group have been performed in terms of modeling accuracy and subjective ratings, respectively. Experimental results indicate that the GDSS group shows much better performance than the traditional group in the realm of OOMD. In particular, when a modeling task is not simple or not structured, the former outperforms the latter. Based on the questionaire, the GDSS group feel more equal status and have less dominant voices than do the non-GDSS group. These facts show that GDSS can be used effectively for OOMD under Korean cultures.

Developing user success metric will make it possible to evaluate the effectiveness of different electronic government systems and will help produce empirical data relating user success to task performance in electronic government environments. The purpose of this study is that combining output-oriented and interaction-oriented variables together into a single model might explain more of the variance in the dependent variable user success in a electronic government than either type of variable could have explained alone. The hypothesized reason is that user success is the result of the reciprocal effects of the properties of the information system and several facets of psychological functioning. Thus, the complex interplay between the system and the user in certain situational contorts may produce different degrees of user success with electronic governments.
