이 논문에서는 호텔예약을 위한 음성번역시스템(KT-STS:Korea Telecom Speech Translation System)에 대해 기술한다. KT-STS는 한국손님이 일본의 호텔을 예약하고자 할 때 사용할 수 있는 시스템으로 한국어 음성을 인식하여 일본어로 번역을 해주는 시스템이다. 이 시스템은 한국어 음성인식부, 한일 기계번역부, 그리고 한국어 음성합성부로 구성되어 있다. 한국어 음성인식부는 HMM(Hidden Markov Model)에 근거한 화자독립, 300 단어급 연속음성인식시스템이다. 언어모델은 바이그램(bigram)을 전향 언어모델로, 의존문법을 후향 언어모델로 사용한다. 기계번역부에서는 의존문법과 직적 번역 방식을 사용하였다. 음성합성부에서 합성단위로 반음소를 사용하며 합성방식은 주기파형분해 및 재배치 방식을 이용한다. KT-STS는 TMS320C30 DSP 보드를 장착한 SPARC20 위크스테이션 상에서 거의 실시간으로 동작한다. 음성인식 실험결과 94.68%의 단어인식률과 82.42%의 문장인식률을 얻었으며, 한일 번역기만의 번역 성공률은 100%였다. 우리는 이 시스템과 일본 KDD에서 개발한 시스템을 전용선으로 연결하여 한일간 자동통역 국제시연을 가진 바 있다.

Recently, the importance of user experience (UX) has been rapidly increasing. Its utilization is emphasized for development of systems, products, and services. User experience is widely used across industries including services, products, processes, society, and culture. Therefore, if it is unsatisfactory, it is likely to have a direct negative impact on the corresponding system, product, or service. The failure to analyze user experience causes significant damage to the project, which may lead to its failure or redevelopment; it is hence necessary to prioritize the verification of UX in the earliest stages of development. The requirements development stage, which is a preceding stage, is an appropriate stage for the verification of user experience because the identification of user needs is completed and prototypes can be implemented. In this paper, we proposed a systematic requirements development stage; it adds user experience verification activities to the requirements development stage, using the Honeycomb model, which is a widely used tool for verifying the overall UX. User experience verification was added to the existing requirements development activities, which consisted of three steps: model definition and requirements placement, discussions between external and internal stakeholders, and review by internal stakeholders. By easily validating the user experience through this systematic requirements development stage, we expect to minimize the damage to the project due to the failure of the user experience analysis and increase the possibility of success.

Since the concept of Manned-UnManned Teaming(MUM-T) and Unmanned Aircraft System(UAS) can efficiently respond to rapidly changing battle space, many studies are being conducted as key components of the mosaic warfare environment. In this paper, we propose a rule-based AI engagement model based on Basic Fighter Maneuver(BFM) capable of Within-Visual-Range(WVR) air-to-air combat and a simulation environment in which human pilots can participate. In order to develop a rule-based AI engagement model that can pilot a fighter with a 6-DOF dynamics model, tactical manuals and human pilot experience were configured as knowledge specifications and modeled as a behavior tree structure. Based on this, we improved the shortcomings of existing air combat models. The proposed model not only showed a 100 % winning rate in engagement with human pilots, but also visualized decision-making processes such as tactical situations and maneuvering behaviors in real time. We expect that the results of this research will serve as a basis for development of various AI-based engagement models and simulators for human pilot training and embedded software test platform for fighter.

As software becomes more complex and its scope dramatically increases, the importance of research on developing methods for estimating software development efforts has been increased. Such accurate estimation has a prominent impact on the development projects. To develop accurate effort estimation models, many studies have been conducted among the academia and the practitioners. Out of the numerous methods, Constructive Cost Model (COCOMO) based on Line of Code (LOC), Regression Model based on Function Point (FP) were the most popular models in the past. As today's development environments are dynamically changing, these traditional methods do not work anymore. There is an impending need to develop an accurate estimation model which accommodates itself to the new environments. As a possible solution, this research proposes and evaluates an software development estimation model based on function points and neural networks.

Naval surface ships and submarines could be exposed to non-contact underwater explosion(UNDEX) environment. Equipment installed on the ships and submarines could be damaged by shock load generated by UNDEX environment. Therefore, shock survivability of equipment generally evaluated by shock tests. Ground based shock test machine such as Light weight shock test machine(LVSM) is developed to simulate shock load caused by UNDEX environment. In this study, linear dynamic model of LVSM is proposed and evaluated to improve shock test design procedure. Parameters of the model are decided by optimizing time domain response compared to zero payload experiment. Proposed model is verified by comparing simulation results and test results of maximum payload experiment. Finally, shock test design using the model is described for various test equipment weight.

Purpose: Domestically, a recent controversial part on Mixed-Use Development is its case that utilizes railroad sites among urban infrastructure. but most of all, a concern is being concentrated on the Mixed-Use Development that uses railroad depot. It has the advantage, which can give diversity and publicness to urban environment by using and planing the upper and bottom of railroad depot, a proximity site as Development Available Land. However, there are few cases except for only Yang-cheon APT in SinJeong railway depot as a domestic case even though a domestic concern about Mixed-Use Development is rising more than ever. Method: Accordingly, this study has something in common with a domestic case, dealing with a case of development in Hongkong that enhances efficiency for city space through Mixed-Use Development and solves various urban problems. Result: A purpose of this study, based on overall comprehension about Rail and Property Model of MTRC in Hongkong, is to figure out how it solve various problems in Mixed-Use Development using Railway Depot or stations in the base of Rail and Property Model of MTRC.

A development scheme for reliable radio-wave Propagation model of digital television (DTV) service, adequate to the domestic environment, is proposed in this paper. Throughout the analysis of several ITU-R recommendations on propagation models in DTV band, ITU-R P.1546, which is based on experimental data, has been selected as our basic model. This model has been programmed, not only to be directly used for engineering analysis, such as frequency assignment, licensing, interference analysis, and sharing frequency bands, but also to be applied for development of a propagation model adequate to the specific environment. Furthermore, the procedure of developing domestic propagation model for DTV service, combined with experimental data which is now being obtained, has been described in this paper.
