This paper intends to propose a technology for recommending convergence/composite art playlist contents that are fused with tags suitable for the user's situational information and taste to users for non-face-to-face art appreciation education. For the implementation of the proposed technology, the characteristics of works of art are analyzed, and related music and works of art are matched based on the tags of the analyzed works. In addition, we would like to propose a technology that automatically creates content for fusion and complex art viewing playlists using matched works.

Recently, many musical instrument mobile apps have been released targeting normal people who can't play musical instrument at all. The reason of developing video system based on step sequencer are as follows; first, users can freely play the musical instruments; second, induce multiple users to play; and third, develop and suggest new step sequencer fused with the video. To resolve issue in video synchronization caused by sync issues when operating multiple step sequencers, the Pocket Operator of Teenage Engineering was used to realize multiply-connected step sequencer and also, the ultimate video system was developed through Mira-Web for multiple participation. In addition, it's required to make the Pocket Operator as software and receive various feedbacks to continue and complement study in order to develop the better video system.

IT 환경이 점차 융 복합화가 되어가면서 소프트웨어 개발 업체들은 다양해진 소프트웨어 개발 영역에 맞춰 소프트웨어 프로세스를 신속하게 적용하는 데 어려움을 겪고 있다. 이와 같은 문제를 해결하고자 본 논문에서는 소프트웨어 개발 업체들이 구축해 놓은 소프트웨어 프로세스 자산을 재사용해 특정 소프트웨어 개발 프로젝트에 적용할 소프트웨어 프로세스를 효율적으로 수립할 수 있는 체계적인 소프트웨어 프로세스 테일러링 절차를 제시한다. 제시한 소프트웨어 프로세스 테일러링 절차를 도입하는 소프트웨어 개발 업체는 소프트웨어 개발 영역에 특화된 소프트웨어 프로세스를 빠르게 수립할 수 있게 됨으로써 정의한 소프트웨어 프로세스를 통해 소프트웨어 개발 프로젝트의 위험 요인들을 사전에 인지할 수 있게 되고 소프트웨어 개발 프로젝트가 예측 불가능한 상태로 진행되는 것을 미연에 통제할 수 있게 될 것으로 예상된다.

We consider about software quality nowadays. The company considers about software quality more and more compare to software development. We analyze the software testing data in this paper. We find the software effect according to the number of testing, the number of testing date, the number of fault according to characteristics. Also, we analyze the result by regression. Also, we propose the testing effect by sex.

The design in this study containing a consideration of children's free fantasy and experiential acquisition, is convergence in terms of its external use of Solar thermal energy and human friendly software, and is about public design based on eco-friendly playing equipments. Despite several flaws, the modularized solar-light power generation equipment is suitable for realizing the concept of the relationship between the Sun and the life thanks to its being versatile. Playing is equivalent to the world for children in itself, therefore; it should be something flexible to stimulate their fantasy and I imagined the sun, which should be something more than a mere source of power generation, and the children interact with each other by the medium of this equipment.

Nowadays, CAD has became an essential tool for designers due to its easy edition and manipulation as well as the capability of communication between designers. Differences between design tool interfaces can cause gaps when visualize designer's ideas. This study is about the differences between various levels of metaphor interface language which is based on the theory of the Hutchins that high-level language interface can reduce the steps of process to visualize the idea of the designers than low-level language interface. This research is based on the assumption that high-level language interface will less interrupt the flow of the design thinking and make more various visual outcomes than the low-level language interface. We verified the hypothesis by analyzing differences of design thinking flow between user groups who used two different animation software. Hopefully, the verification of the hypothesis in this study can be able to guide the use pattern of the CAD tools.

Today the computerization in overall civil life is globally progressing, and software plays a central role in all interdisciplinary areas of society. These changes of information environments lead to the change of values and paradigm shift, and the change of Korean educational policies is also happening. As human-machine interaction is becoming ubiquitous, code literacy is going to play an important role before long. Despite these transitions, information education in universities in Korea focuses on just driving application programs. In this paper, we explore overall educational system and curriculum of universities in Korea. And we present educational factors corresponding to educational levels and contents. Presented five factors coupling three educational contents and three educational levels may be dedicated to design curriculum.

Since the elderly voices include a lot of noise caused by physiological changes in respiration, phonation, and resonance, the performance of the convergence health-care equipments such as speech recognition, synthesis, analysis program done by elderly voice is deteriorated. Therefore it is necessary to develop researches to operate health-care instruments with elderly voices. In this study, a voice activity detection using a symmetric higher-order differential energy function (SHODEO) was developed and was compared with auto-correlation function(ACF) and the average magnitude difference function(AMDF). It was confirmed to have a better performance than other methods in the voice interval detection. The voice activity detection will be applied to a voice interface for the elderly to improve the accessibility of the smart devices.

Despite agile methods and software reuse being distinct approaches, there has been a growing amount of research on combining these approaches. Although Scrum is one of the most popular agile methods, reuse has not been actively supported. In this paper, we identify a new type of reusable Scrum assets, simplify the backlog process and propose a backlog factoring technique by extending task factoring to support reuse in the Scrum method. In addition, we can apply the proposed technique and show prototyping of backlog reuse in e-business applications.
