  • The purpose of this study is to research the process of Korean students' acquiring the indefinite article. To research this , we will propose two subjects of study as below. The first subject is that we will examine whether there will be any differences of the acquisition in the indefinite article between gender, male and female. The second subject is that we will examine whether there are any differences of the acquisition by the degree of proficiency at English. The subject of a sample survey was 115 female and 80 male students, total 195 students, who take English courses as a required subject at 'C' university in Gwangju. The necessary data for this study was obtained by the Questionnaires with 19 questions about the indefinite article. The data analyzing method was ANOVA(analysis of variance between groups) through the statistics program SPSS 12.0. As a consequences of this study we found that the side of the acquisition in the indefinite article between gender, male and female is closely related in the data result of the questions and the side of the acquisition by the level of proficiency at English has the meaningful data result of 14 questions at the questionaries.

  • Nowadays, Internet is so popular that we can easily access the remote site to search information and to communicate remote site and users. People who want to make a collaborate working environment can use JAVA, CORBA, and other internet programming tools like a Perl/XML. The mechanist are try to make the environment fur collaboration within design/manufacturing, simulation, remote sensing through TCP/IP And many industries and research institutions are working towards the agile manufacturing. This paper describes an internet-based real-Time remote monitoring system. The system consists of a hardware setup and a software interface. The hardware setup consists of a machine and its data acquisition hardware, while the software interface incorporates the data acquisition software, the server program, and the client program. The server program acts as the main interface between the data acquisition system and the internet technology. The client program is to be distributed to the remote users who want to monitor the machining status. The system has been demonstrated and verified for an industrial High-Speed Machine (HSM) especially measuring cutting force and acoustic emission. To share the signal, we make the WWW server and display its value. The system has been found to be highly efficient, reliable and accurate.

  • Systematic performance evaluation of the Defense Acquisition Program is very important, since they are directly related to national security. In this paper, we reviewed various performance evaluation models from a methodological perspective for pragmatic performance evaluation, and the limitations of each model. In order to evaluate the performance of the Defense acquisition program efficiently, especially for the Naval ship Projects and considering their unique characteristics, both various stakeholders' participation, standard indicators for performance measurement, and tailoring them considering the projects' circumstances are necessary. We also propose indicators, contents, and detailed criteria example for the Requirements management. This approach enables a pragmatic and consistent evaluation of defense projects, and through this, meaningful insights could be acquired with accumulate data.

  • This study aims to verify experimentally the specifications of the data acquisition system required for the precise measurement of signals in an underwater explosion (UNDEX) experiment. The three data acquisition systems with different specifications are applied to compare their precision relatively on maximum shock pressures from UNDEX. In addition, a method of assessing the acquired signals is suggested by introducing the concept of measurement uncertainty. The underwater explosion experiments are repeated five times under same conditions, and assessment is conducted on maximum quantities acquired from underwater pressure sensors. It is confirmed that the concept of measurement uncertainty is very useful method in accrediting the measurement results of UNDEX experiments.

  • To develop reliable 3D face recognition system, many researchers also have focused on 3D face data acquisition system. Previous many 3D face acquisition systems use visible patterns to solve corresponding problem, and this pattern made anyone who wants to be verified uncomfortable. In this paper, we propose a new invisible infrared line-laser pattern for 3D face data acquisition.

  • The L2 Civil Signal (L2CS) will be transmitted by modernized IIR(IIR-M), IIF and all subsequent GPS satellites. It contains two codes of different length; CM code contains 10,230chips, repeats every 20milliseconds and is modulated with message data, and CL code contains 767,250chips, repeats every 1.5second Z-count and has no data modulation. And the message data is encoded for Forward Error Correction(FEC). The long code length is useful for weak signal, but it also requires very long acquisition time. Therefore, the structure of GPS Ll/L2C Correlator and the fast acquisition scheme are proposed in this paper.

  • In order to provide healthcare services based on context-awareness techniques in IoT environments, a system requires to collect user profile and environmental information. To collect environmental information, accessing sensor device and gathering sensor data should be proceeded. Although this process is necessary to build environmental information, there is no proper sensor data acquisition model. In this paper, we propose sensor data acquisition model that contains schema to connect each device and to collect various kinds of data from sensor device at one point. In experiment, we demonstrate sensor data acquisition procedures with a description following suggested scheme.

  • This research is to understand luxury consumption values for luxury consumers. The aims of this study is to identify their luxury consumption values and the effects of the values on the perceived acquisition value. This study also divided data into two groups according to the difference between reservation price and actual price; positive reservation price group, negative reservation price group, and analyzed the effects of the values on the perceived acquisition value between two groups. In this study, we used structural models equation and results presented that the conceptual model was a good fit to the data. The empirical results suggested four dimensions of luxury consumption values; symbolic value, innovative design value, quality value and origin value. There were positively significant effects of symbolic value and quality value on the perceived acquisition value. The effects of innovative design value on the acquisition value was significantly negative. Two groups categorized by reservation price depicted the differences on effect levels of symbolic value, innovative design value, and quality value on the acquisition value perception.

  • Comtemporary firms need capability of acquiring external knowledge and internalizing it to cope with environmental fluctuation. The paper analyzes the impact of absorptive capacity, an ability to recognize and utilize external knowledge, on knowledge acquisition of the firm, and examines the role of trust in the knowledge acquisition process. Data were collected from 84 domestic companies that had adopted ERP packages. The results indicate that prior experiences of knowledge acquisition, communication mechanism, and conflict resolution mechanism affect knowledge acquisition positively. Among those independent variables, communication mechanism and conflict resolution mechanism significantly and positively related with trust. Trust is, in turn, positively associated with knowledge acquisition. Meanwhile, previous knowledge base and prior relationship with the knowledge provider do not affect knowledge acquisition. Further, the results provide evidence that trust plays a mediating role between other absorptive capacity factors and knowledge acquisition.

  • For developing new algorithms or dedicated hardware by using general purpose Digital Signal Processor chip, emulator H/W and simulator S/W are indispensible. But the most of DSP emulators have limitations on H/W flexibility according to their generalized architectures. In this paper, a DSP evaluation system for real time signal processing was developed using TMS 32020. The I/O buffers storing acquisition data of the system were designed to have variable length $(1\sim2048samp1es) &$ sampling frequency $l00\sim8KHz$.
