축산농가의 경제성과 직결되는 암소 발정기의 조기 탐지는 IT 농 축산 학계에서도 매우 중요한 문제 중 하나이며 반듯이 해결해야만 하는 문제로 알려져 있다. 이를 해결하기 위한 다양한 연구 방법들 중, 본 논문에서는 소리 센서 환경에서의 암소의 발정기 탐지 시스템에 관한 연구를 대상으로 한다. 특히, 발정기 발성음의 특징 벡터 생성에 초점을 맞춘다. 특징은 크게 분별력과 차원이라는 두 가지 기준에 대해 우수해야 한다. 즉, 좋은 특징이란 서로 다른 부류를 잘 분별해 주어야 할 뿐만 아니라, 특징 벡터의 차원이 낮을수록 계산 효율이 좋고 차원의 저주에서 멀어 진다. 본 논문에서는 통계학에 기초한 체계적인 특징 벡터 생성에 관한 알고리즘을 제안하고, 실제 축사에서 녹취한 한우 발정기 발성음을 대상으로 낮은 차원의 특징 벡터 생성 과정을 보인다. 또한 이상상황 탐지기로 잘 알려진 단일 클래스 SVM의 대표 모델인 SVDD를 탐지기로 설정하여 생성된 특징 벡터의 분별력을 실험적으로 검증한다.

Oral history has value that steps over the class consciousness and party feeling that records have, and enables a general representation of a human experience. Beside, It must be managed urgently because a collection of oral history has unique and limited. However, domestic related institution do not keep management for release and use of oral history in their mind are only concentrating on accession. Lately, National History Compilation Committee passes through faithful planning procedures and is collecting an oral history collection project. A merit of this project is to have attempted an image photographing. This study is propose that to examines over the all steps to say oral history collection activity to information service and a preservation from collection planning of organization. However, this study is insufficient in the management method how it is connected if does in order to manage the oral history which is collected with a part of a record in a archival institution because this study was only for the purpose of management of oral history. This problem will be studied through a process of checking the real thing of oral history.

Internet telephony is an Internet service which supports voice telephone using VoIP technology on the IP-based Internet. It has some advantages in that voice telephone services can be accompanied with multimedia services such as video communication and messaging services. Recently, the introduction of smart phones has led to a growth in social networking services and thus, the research and development of Internet telephony has been actively progressed and has the potential to become a replacement for the telephone service that is currently being used. In this paper we designed and implemented an Internet telephony network system which is developed by using Asterisk and open source softwares. It is developed on the linux system and has some features such as VoIP telephony service between SIP phones, voice mail, and call recording. It also supports web-based functions such as SIP users and server system management that is implemented by Apache web server and PHP programs. Afterwards, this system will be applied as VoIP network base technology for small sized companies and organizations. It will paly a role for encouraging companies to use open source softwares.

This study is a qualitative study using focus group interview to explore the perception regarding smartphone use for adhering to self-care in chronic heart failure patients. Eleven patients who were diagnosed with heart failure were included. Three focus groups were held with heart failure patients at an outpatient cardiac care center. The focus group discussions were transcribed verbatim and analyzed using the method of constant comparative analysis. The 12 sub-themes were categorized into 'perception of smartphone use', 'Barriers to smartphone use', and 'Facilitators to smartphone use'. We found that the need to design tailored the messages or health information based on individual preferences. Our findings will be used to develop or design a smartphone based self-care program for patients with heart failure.

Multimedia needs and searching have become important in everyday life, especially in a younger generation. The characteristics of multimedia needs and searching behaviors are distinctive compared to textual information needs and searching behaviors in a wide variety of ways. By interviewing and observing multimedia needs and searching behaviors of college students from 20 areas in Seoul, this study aims to improve the understanding on users' multimedia needs and how users search multimedia. The findings are presented in terms of searching sources, multimedia needs, relevance criteria and searching barriers. For multimedia, the searching sources are found primarily as Naver and Google and the distinguished features are presented depending on the individual multimedia types. As multimedia needs are categorized into generic, specific and abstract, most of the needs are classified as specific needs rather than generic needs, but there exist differences depending on the types of multimedia. In addition, the aspects of relevance criteria and searching barriers are reflected with the characteristics of individual multimedia types. The findings of this study demonstrate that distinctive indexing and searching environments depending on the types of multimedia might be necessary to improve the quality of multimedia searching.
