This paper describes the software download framework for SDR(Software Defined Radio). SDR is expected to solve the compatibility problem among various mobile communication standards so that people can use the same device for different wireless network. We integrated the SDR software download process into Jini architecture, and modified Jini's several functions. We implemented this proposed framework on a Linux and windows operating systems with Java programming language. With Java platform, we can easily transfer this framework into hand-held devices.

The study examined how changes in time invested in private tutoring and academic achievement influenced each other through a multivariate latent growth model by using the data from the first to the third year presented in the KYPS. This study identifies not only how changes in the private tutoring experience exerted a direct influence on changes in academic achievement, but also measures what kind of changes in private tutoring and academic achievement had emerged over time. The detailed study results are as follows. First, the analysis of time invested in private tutoring showed that the higher the grades, the greater were the amount of time invested in private tutoring in the case of Korean language study. On the other hand, the results showed that in the case of English and mathematics, the higher the grades, the lesser was the amount of time invested in private tutoring. Second, private tutoring and academic achievement were all in a linear relationship. Third, it was shown that the time invested in private tutoring and academic achievement exerted a negative influence on each other according to the passage of time.

This paper is aimed at the investigation of pragmatic contributions to the identification of explicatures. An explicature is the result of fleshing out the semantic representation of an utterance. The basic assumption of the paper is that the process of the developing the semantic representation into an explicature depends heavily on contextual information. Therefore, we are concerned with the way in which hearers use contextual information to flesh rut or develop the semantic representation of an utterance. The identification of explicatures includes both the recovery of the proposition expressed and the recovery of what we called higher-level explicatures. There are three subtasks involved in the recovery of the proposition expressed: reference assignment disambiguation and enrichment On the other hand, there are two subtasks involved in the recovery of higher-level explicatures: attitudes and speech acts.

After investigating repeatedly results obtained through gear stress analysis, we make a determination of an optimal gear shape. But its design process was not only complex but also difficult to get a precise profile curve from operating by hand. In this study, relating shape of gear profile curves was generated automatically with standard spur gear, equivalent helical gear, shifted gear & pinion by using developed program which is using Auto_LISP language in Auto-CAD. This program which can design rapidly gear shapes will successfully support gear designing and manufacturing fur Small & Medium companies.

본 논문은 최근 연구가 고조되고 있는 지적 인터페이스에 대한 연구로서, 장애인 복지와 공학적인 일반성을 고려하여 수화를 인식하였다. 장애인의 수화를 인식한다는 입장에서 심리적 부담을주지 않고 최소한의 제한조건만을 설정하여 수화의 흑백동영상을 입력으로 하였다. 수화인식에서 손의 형상과 움직임 방향정보가 제일 중요함을 감안하여 각각 그 정보를 추출하고 인식에 적용하는 방법을 개발하여 그 유효성을 보였다. 즉 형상정보의 추출 및 인식에 대해서는 형상정보만이 중요한 수화 지문자 자음 14자를 대상으로 하여 인식하는 과저을 보였다. 또한 손의 움직임 정보에 대해서는 움직임 방향마이 중요한 정보가되는 간단한 수화 단어 9개를 대상으로 인식하여 그 과정과 방법을 보였다.

Recently, the system of the industry demands quick and accurate measurement for the mass production and high quality. Also, we need to improve the accuracy to decrease the failure rate in automatic assembly processing and improve the confidence, durability and the compatibility of parts. To answer this tendency and requirement, we have developed many accrate measuring instruments and methods. In this paper, we develop the whidows program using the DSP board(TMS320C25) which is used the data acquisition and the Visual C $^{++}$ , a windows programming language. We perform the measurement, analysis and output process in GUI(Graphic User Interface)environment. By using system, we will save the time required for the hand-worked measurement and avoid the useless iterative measurement. Furthermore, we expect to improve the productivity through automotive quality control in manufacturing process.s.

감성 분석에서 어휘 말뭉치는 기존의 전통적인 기계학습 방법에서 중요한 특징으로 사용되었다. 최근 딥러닝의 발달로 hand-craft feature를 사용하지 않아도 되는 End-to-End 방식의 학습이 등장했다. 하지만 모델의 성능을 높이기 위해서는 여전히 어휘말뭉치와 같은 특징이 모델의 성능을 개선하는데 중요한 역할을 하고 있다. 본 논문에서는 이러한 어휘 말뭉치를 Attention 모델과 $Na{\ddot{i}}ve$ bayes 모델을 기반으로 구축하는 방법에 대해 소개하며 구축된 어휘 말뭉치가 성능에 끼치는 영향에 대해서 Hierarchical Attention Network 모델을 통해 분석하였다.

In this paper, we propose an expert system for electronic interlocking which enhances the safty, efficiency and expanability of the existing system by designing real-time interlocking control based on the interlocking table automatically generated using artificial intelligence approach. The expert system consists of two parts; an interlocking table generation part and a real-time interlocking control part. The former generates automatically the interlocking relationship of all possible routes by searching dynamically the station topology which is obtained from station database. On the other hand, the latter controls the status of station facilities in real-time by applying the generated interlocking relationship to the signal facilities such as signal devices, points, track circuits for a given route. The expert system is implemented in C language which is suitable to implement the interlocking table generation part using the dynamic memory allocation technique. Finally, the effectiveness of the expert system is proved by simulating for the typical station model.

This paper describes a cell programming environment that deals with problems associated with programming Flexible Manufacturing Cells(FMCs). The environment consists of the cell programming editor and the automatic generation module. In the cell programming editor, cell programmers can develop cell programs using task level description set which supports task-oriented specifications for manipulation cell activities. This approach to cell programming reduces the amount of details that cell programmers need to consider and allows them to concentrate on the most important aspects of the task at hand. The automatic generation module is used to transform task specifications into executable programs used by cell constituents. This module is based on efficient algorithm and expert systems which can be used for optimal path planning of robot operations and optimal machining parameters of machine tool operations. The development tool in designing the environment is an object-oriented approach which provides a simple to use and intuitive user interface, and allows for an easy development of object models associated with the environment.

The purpose of this study was to develop a computer program to draft princess line onepiece dress pattern. To this study, the Turbo Pascal Compiler and the Pascal language were used. The procedures of the study were as follows: 1. A basic onepiece dress pattern was drafted by the hand operation. 2. The co-ordinate points were instituted for indication of relative position of all necessary points in drafting. Total sixty-nine co-ordinte points (front: thirty-five, back: thirt-four) were instituted. 3. The two subprograms for main program were developed to solve geometric problems and to draft straight lines and curved lines of the onepiece dress pattern. 4. The program was accomplished by putting indivisual body measurement 5. Grading fo five size was given.
