Recently, large-scale language models (LPLM) have been shown state-of-the-art performances in various tasks of natural language processing including intent classification. However, fine-tuning LPLM requires much computational cost for training and inference which is not appropriate for dialog system. In this paper, we propose compressed intent classification model for multi-agent in low-resource like CPU. Our method consists of two stages. First, we trained sentence encoder from LPLM then compressed it through knowledge distillation. Second, we trained agent-specific adapter for intent classification. The results of three intent classification datasets show that our method achieved 98% of the accuracy of LPLM with only 21% size of it.

Java language is a representative object-oriented language that is used at the various platform and fields. A structure of java language is simpler than traditional procedural-oriented language because of characters of object-oriented language But it is difficult to debug complicated java programs. Debugging has always been a costly part of software development. Syntax errors of java programs is easily found by the current debugging system. But it is difficult to locate logical errors included in java programs. Traditional debugging techniques locating logical errors in java program have been still used with conventional methods that are used at procedural-oriented languages. Unfortunately, these traditional methods are often inadequate for the task of isolating specific program errors. Debugger users may spend considerable time debugging code of program development with sequential methods according as program size is large and is complicated. It is important to easily locate errors included in java program in the software development. In this paper, we apply algorithmic debugging method that debugger user can easily debug programs to java program. This method executes a program and makes an execution tree from calling relation of functions. And it locates errors at the execution tree. So, Algorithmic debugging method can reduce the number of debugging than conventional sequential method.

Unit testing which is the first task to perform software testing has a major impact on reducing s/w development cost and improving s/w quality. In order to make unit testing become the formal procedure rather than ad-hoc tasks performed by developer, the language-neutral measures are necessary in the programming which is able to specify the test cases. This paper presents a test assertion language for the language-neutral specification of the test cases. The suggested language is based on the ISO/IEC 24709-1, but it supports object oriented features and can describe test cases for unit testing. The test cases that are specified by the language can be used for generating test oracle source codes by test oracle generation tools.

An object-oriented design was carried out for the digital photogrammetric processes. Classes were identified and implemented to develop an integrated digital photogrammetry system using a 3 dimensional self-calibration model for CCD cameras. This integrated system is deemed to be a significant progress from the conventional photogrammetric system which is a series of discrete processes. Object oriented methodology was selected for the implementation of the integrated photogrammetric system because it would be a very complex task to get the same result using a procedural programming language. Besides the simplification of development effort, object oriented methodology has further benefits of better management of program in case when updates to parts of the program are necessary. Using the classes designed in this study, a 3 dimensional self-calibration model was developed for a CCD camera. Classes for data input and image handling as well as classes for bundle adjustment were implemented. The bundle adjustment system was further enhanced with member functions to handle additional parameters for principal point coordinates and focal length, thereby, enabling the application to non-metric CCD cameras.

This paper proposes a searching system with a mobile agent which retrieve data from the distributed hosts. The proposed system dispatched the movable objects, so called AGLET, to the distributed hosts in order to perform a task given by a client or a server. The network of the existing system must not be disturbed during a task is performing. However our system has the strong point that a task can be performed even if the network is disconnected on the way. When the network is disconnected, the system can get the results later after the network system is connected again. Designing the system has been done by using UML(Unified Modeling Language) which is a standardized object-oriented modeling language. AGLET, a pure JAVA product of IBM, is used for the mobile agent.

The demands of increasingly complicated software have led to the proliferation of object-oriented design methodologies in embedded systems. To execute a system designed with objects in target hardware, a task set should be derived from the objects, representing how many tasks reside in the system and which task processes which event arriving at an object. The derived task set greatly influences the responsiveness of the system. Nevertheless, it is very difficult to derive an optimal task set due to the discrepancy between objects and tasks. Therefore, the common method currently used by developers is to repetitively try various task sets. This paper proposes Scenario-based Implementation Synthesis Architecture (SISA) to solve this problem. SISA encompasses a method for deriving a task set from a system designed with objects as well as its supporting development tools and run-time system architecture. A system designed with SISA not only consists of the smallest possible number of tasks, but also guarantees that the response time for each event in the system is minimized. We have fully implemented SISA by extending the ResoRT development tool and applied it to an existing industrial PBX system. The experimental results show that maximum response times were reduced $30.3\%$ on average compared to when the task set was derived by the best known existing methods.

대화 시스템에서 대화 상태 추적은 사용자와의 대화를 진행하면서 사용자의 의도를 파악하여 시스템 응답을 결정하는데 있어서 중요한 역할을 수행한다. 특히 목적지향(task-oriented) 대화에서 사용자 목표(goal)를 만족시키기 위해서 대화 상태 추적은 필수적이다. 최근 다양한 자연어처리 다운스트림 태스크들이 사전학습 언어모델을 백본 네트워크로 사용하고 그 위에서 해당 도메인 태스크를 미세조정하는 방식으로 좋은 성능을 내고 있다. 본 논문에서는 한국어 토큰-프리(token-free) 사전학습 언어모델인 KeByT5B 사용하고 종단형(end-to-end) seq2seq 방식으로 미세조정을 수행한 한국어 생성 기반 대화 상태 추적 모델을 소개하고 관련하여 수행한 실험 결과를 설명한다.

Robot programming has been discussed in detail during the recent years. Numerous studies in particular presented relevance, solution concepts and implementation of off-line programming. In this paper a new user-friendly robot programming method is introduced, which permits the implicit description and programming of assembly process. On the functional level of programming, the assembly processes are described in terms of their operational functions. On the language level, the individual functions are then translated into commands for the robots.

The purpose of this paper is to analyze the recent trends of the development of the English textbooks in EFL situation. The 7th National English Curriculum(NEC) in 2001 which emphasized the curriculum-centered school education have had much influence on the traditional textbook-centered school education in Korea. According to the paradigmatic change of school education, the contents of the English textbooks were changed into the new types of students-centered classroom activities. For students' communicative activities, the English textbooks were developed by two types of syllabuses: process-oriented syllabus and product-oriented syllabus. The 7th NEC includes procedural syllabus and task-based syllabus as well as grammatical- structural syllabus and notional-functional syllabus. In short, unlike the English textbooks in former curriculums, learners' classroom activities and tasks have been emphasized in those to foster their communicative competence.
