Quality of software development project is very important In complex and large domestic soft ware markets. CMM level certification evaluates duality of software development project at present. Therefore, software development company endeavor for acquisition of CMM certification, level up CMM and organization's competitive power But, today confidentiality of CMM certification come into question, an exploratory study undertake about difference of software project quality and organization performance between CMM certificated organization and no-CMM certificated organization. Two organizations different partially. First of all, incremental improvement of software project process takes precedence of CMM certification. It is better to fit between culture of organization and CMM certification for project quality.

This study attempted to extract and structure the job skills required for 3D designers, which have been recently introduced to the fashion industry. The study aimed to materialize and objectify the 3D designer's job, using a focus group interview for the survey. The 3D designer has the TD task of making 3D virtual samples using the pattern files developed in Pattern CAD. Graphic design and fabric digitization are also major tasks for the 3D designer. CLO is mainly used for 3D virtual sample production, and PixPlant, Substance, Photoshop, Cinema 4D, Daz studio, and 3ds MAX are used for image and avatar editing. As per the job skills required for 3D design work, basic knowledge about patterns and sewing, skill in 3D virtual clothing technology, ability to use various software, and English skills were considered important, in that order. In particular, the need for knowledge about patterns and sewing became more important than the skill in 3D virtual clothing technology itself. To train 3D designers, it was found that not only 3D virtual clothing software, but also education on patterns and clothing construction, CAD developer's curriculum certification system, and 3D designer qualification management were required. In addition, 3D designers are recognized as an essential job in fashion vendors, and the demand for domestic brands is increasing. The biggest limitation of the 3D virtual clothing system is the perfection of the digital fabric. Also, technical improvement is needed.

Ubiquitous computing spans a very broad range of technologies and needs very complicated user's requirements. There are many scenarios and technologies involved in ubiquitous computing. We need new software development tools and methodology to meet the requirements. A software product line is one of promising new technology for it. A software product line is a set of software intensive systems that share a common, managed set of features satisfying the specific needs of a particular market segment or mission and that are developed from a common set of core assets. Software architecture-based development is the exploration and maturation of the role of software architecture in the product line life cycle. In this thesis, we identify the foundational concepts underlying software product lines and the essential activities to develop the mobile application systems. So, we define, design, and implement the Mobile Application System Architecture(MASA) that includes the development process for applying into mobile business domain and encompass scoping and gathering requirements for the Product line based on Component Based Development(CBD).

Software reliability growth models are used in testing stages of software development to model the error content and time intervals between software failures. This paper presents a stochastic model for the software failure phenomenon based on a nonhomogeneous Poisson process(NHPP) and performs Bayesian inference using prior information. The failure process is analyzed to develop a suitable mean value function for the NHPP ; expressions are given for several performance measure. Actual software failure data are compared with several model on the constant reflecting the quality of testing. The performance measures and parametric inferences of the suggested models using Rayleigh distribution and Laplace distribution are discussed. The results of the suggested models are applied to real software failure data and compared with Goel model. Tools of parameter point inference and 95% credible intereval was used method of Gibbs sampling. In this paper, model selection using the sum of the squared errors was employed. The numerical example by NTDS data was illustrated.

현재 소프트웨어 산업에서 자연어 요구사항의 정확한 분석 연구는 활발히 진행되고 있다. 그러나, 문법적인 분석만을 통해 해석하는 것이 일반적이다. 본 연구는 요구공학과 언어학 그리고 카툰 공학을 접목을 제안한다. 이를 위해서, 1) 언어학적 관점에는 촘스키의 구문 구조 분석 이론과 필모어의 의미역 이론을 결합하여 문법적, 의미적 분석을 수행한다. 2) 요구공학 관점에서는 요구사항 분석으로 상태 모델 속성 추출 및 접목한다. 3) 카툰 공학에서는 3D 이미지 생성한다. 또한, 해결 못했던 동사와 형용사에 대해 분석하여 범위를 확장한다. 즉 언어학적 분석을 바탕으로 UML 상태 다이어그램을 추출하고, 이를 3D 상태 이미지 생성한다. 본 연구는 AI 기술(Text to Image)에 소프트웨어 공학적 방법에서의 절차적인 공정과 재사용 적용함으로써, AI 내부 작동 원리에 대해 체계적으로 연구하고자 한다.

Due to rapid socio-economic development and environmental changes, particularly autism spectrum disorder (ASD) in the context of Attention Deficit Hyperactivity Disorder (ADHD) and high-functioning autism, has become a significant social issue. This issue is increasingly recognized from a societal perspective rather than just an individual or family problem. But there remains a lack of information in frontline education. Traditionally, treatment for ASD has been conducted in specialized institutions, or by professional doctors, therapists, and counselors. There are still several challenges such as 1) accessibility to hospitals and transportation for children with ASD, 2) the maturity and competence of therapists, and 3) the lack of appropriate educational content. To solve these problems, we propose a supplementary 3D educational game process for children with high-functioning autism that utilize speech recognition technology and games designed for continuous and repetitive learning. Our proposed game content can be used at home, which incorporates Speech-To-Text (STT) technology and mini-games to help children indirectly experience and learn to handle unexpected real-life situations. With this approach, we will expect that the children can develop social skills and enhance the efficiency of their treatment.

We explored the method of teaching and learning of 3D based software which is useful for 3D content's authoring and utilization as a suitable tool of teaching and learning for 'Smart Learning' environments. To investigate the possibility of application in the field, we applied this software to 'Smart School' temporally. After that, we conducted a survey of learning satisfaction of students, and assessed the possibility of application in the field via one-on-one talk with teachers. As a result, we drew a positive conclusion for the applications, which are instructional medias in various subject areas, presenting materials for motivation, a tool for individual or cooperative presentation, and instructional medias for underachieving students or gifted students.

본 논문에서는 저성능 컴퓨터나 스마트폰의 카메라를 통해 입력받은 영상을 기반으로 사용자의 포즈를 추정하고, 실시간으로 사용자의 포즈에 따라 3D 모델의 모션이 제어되어 가시화 될 수 있는 클라이어트-서버 구조의 "자세추정 및 3D 모델 모션 제어 시스템"을 제안한다. 제안 시스템은 소켓통신 기반의 클라이언트-서버구조로 구성되어, 서버에서는 실시간 자세 추정을 위한 딥러닝 모델이 수행되고, 저성능 클라이언트에서는 실시간으로 카메라 영상을 획득하여 영상을 서버에 전송하고, 서버로부터 자세 추정 정보를 받아 이를 3D 모델에 반영하고 렌더링 함으로써 사용자와 함께 3D 모델이 같은 동작을 수행하는 증강현실 화면을 생성한다. 고성능을 요구하는 객체 자세 추정 모듈은 서버에서 실행하고, 클라이언트에서는 영상 획득 및 렌더링만을 실행하기 때문에, 모바일 앱에서의 실시간 증강현실을 위한 자세 추정 및 3D 모델 모션 제어가 가능하다. 제안 시스템은 "증강현실 기반 영상 찍기 앱" 에 반영되어 사용자의 움직임을 따라하는 3D 캐릭터들의 영상을 쉽게 생성할 수 있도록 할 수 있다.

1992년 id Software가 최초의 3차원 게임인 Wolfenstein 3D(그림 1)를 선보인 이래, 3차원 게임은 게임 시장에서 주류의 자리를 차지하게 되었다. 저사양의 하드웨어에서 구동되는 모바일 게임을 제외하고는 현재 대부분의 게임이 3차원으로 제작된다고 보아도 무방할 것이다. 이 같은 시장 수요에 부응하여 다수의 3차원 렌더링 엔진이 개발되었는데, 대표적인 것으로는 id Software의 Doom Ⅲ, Criterion의 Renderware, Epic Games의 Unreal Ⅱ 및 Ⅲ, Intrinsic의 Alchemy, NDL의 GameBryo 등이 있다.
