This study is to investigate and analyze on the status and problems of knowledge & information contents management in the financial institution of Korea. The domain of research was made of user library, and archives management. The result of the study was as follows: 1) to provided knowledge & information contents on user. 2) to generated the problems on utilization and production knowledge & information contents as the lack of understanding 3) to had little understanding on knowledge information share and management. For example, to differ archives management and library. So, the researcher proposed an active programs on the above problems.

스마트폰, 태블릿 PC 등 정보 기술의 급속한 확대로 주파수 수요가 증가하여 세계 각국은 모바일 데이터 트래픽 수용을 위한 주파수 확보에 노력하고 있다. 미국은 원활한 주파수 확보를 통한 초고속 광대역 통신망의 확충이 통신 분야에서 미래 국제 경쟁력 확보에 필수적이라는 것을 인식하고, 새로운 대역에서 모바일 주파수를 확보하는 노력뿐 아니라 기존 대역에서 1차 사용자를 보호하며 공유할 수 있는 공유 주파수 자원의 확보도 추진하고 있다. 주파수 공유를 도입하면 필요한 주파수를 짧은 기간에 경제적인 가격으로 확보 가능하다는 장점이 있다. 본고는 미국에서 주파수 공유를 위해 도입하는 최근의 스펙트럼 정책 동향에 대해 기술하고자 한다.

Traditionally, a domestic construction industry has recognized the relationship between a primary contractor and a subcontractor as a subordinated trade connection. To improve this unfair connection, the primary contractor and subcontractor's relationship must be recognized as Co-Development, and a new construction circumstances are needed, too. To apply benefit sharing to this relationship for Mutual Corporation, this needs the application method which could be reflected the specific aspects such as construction production method and production organization. Therefore, this study is aimed for the suggesting of basic data for Benefit Sharing application in the domestic construction industry by researching the problems and Benefit Sharing application States.

본 연구에서는 KM-Net(Hidden Markov Network)을 다양한 태스크에의 적용과 화자의 특성을 효과적으로 나타내기 위해 HM-Net 음성인식 시스템에 MLLR(Maximum Likelihood Linear Regression) 적응방법을 도입하였으며, HM-Net 학습 알고리즘을 개량하여 회귀클래스 생성방법을 제안한다. 제안방법은 PDT-SSS(Phonetic Decision Tree-based Successive State Splitting) 알고리즘의 문맥방향 상태분할에 의한 상태레벨 공유를 이용한 방법으로 새로운 화자로부터 문맥정보와 적응화 데이터의 발성 양에 의존하여 결정된 많은 적응 파라미터들을(평균, 분산) 자유롭게 제어할 수 있게 된다. 제안방법의 유효성을 확인하기 위해 국어공학센터(KLE) 452 음성 데이터와 항공편 예약관련 연속음성을 대상으로 인식실험을 수행한 결과, 전체적으로 음소인식의 경우 평균 34-37％, 단어인식의 경우 평균 9％, 연속음성인식의 경우 평균 7-8％의 인식성능 향상을 각각 보였다. 또한 적응화 데이터의 양에 따른 인식성능 비교에서, 제안방법을 적용한 인식 시스템이 적응 데이터의 양이 적은 경우에도 향상된 인식률을 보였으며. 잡음을 부가한 음성에 대한 적응화 실험에서도 향상된 인식성능을 보여 MLLR 적응방법의 특성을 만족하였다. 따라서 MLLR 적응방법을 도입한 HM-Net 음성인식 시스템에 제안한 회귀클래스 생성방법이 유효함을 확인한 수 있었다.

In vocabulary recognition systems based on HMM(Hidden Markov Model)s, training process unseen model bring on show a low recognition rate. If recognition vocabulary modify and make an addition then recreated modeling of executed database collected and training sequence on account of bring on additional expenses and take more time. This study suggest efficient context dependent process modeling method using decision tree-based state tying. On study suggest method is reduce recreated of model and it's offered that robustness and accuracy of context dependent acoustic modeling. Also reduce amount of model and offered training process unseen model as concerns context dependent a likely phoneme model has been used unseen model solve the matter. System performance as a result of represent vocabulary dependence recognition rate of 98.01%, vocabulary independence recognition rate of 97.38%.

Established continuous vocabulary recognition system improved recognition rate by using decision tree based tying modeling method. However, since system model cannot support the retrieve of phoneme data, it is hard to secure the accuracy. In order to improve this problem, we remodeled a system that could retrieve probabilistic model from continuous vocabulary clustering model to phoneme unit. Therefore in this paper showed 95.88%of recognition rate in system performance.

The purpose of this study is to scrutinize the copyright issue under Open Access environment. A survey has been carried out to investigate researchers' awareness and recognitions about such issues. For this, bioinformatics researchers were selected and surveyed. Descriptive statistics method is employed for analysis of collected data. The findings of this study summarized as follow. (1) Although the researchers regarded the Open Access a positive initiative, the perceptions about open access were very low. (2) The researchers demanded possession of copyright depending on type of research information. (3) Many agencies did not required the transfer of copyright to the researcher. Thus, there is a possibility of dispute regarding copyright issues between researchers and agencies. (4) The researchers are willing to participate in open access activity on the assumption that their study is used in legitimate objective. On the basis of these findings, suggestions are added in as an impetus to lower the barrier against a copyright and higher the approach to information seekers and information providers.

In knowledge-based society, it is understood that the knowledge is an essential resources for effective management of the organization. Lately, knowledge management has been accepted by many organization as a new theory of management. But the problem is that people, a component of the organization tend not to open their own knowledge to others, but to keep seeking knowledge of others. It can be found in many research papers that there have been very little efforts for sharing knowledge among members of organization. The purpose of the study is to investigate the reasons for not sharing knowledge or ideas with others, to identify some cultural factors effecting their closed-minded attitude towards the sharing knowledge, and to find the solutions from the organizational culture.

This study aims to provide basic information on how to secure competitiveness of companies from a practical point of view by examining how information sharing for companies' infection prevention and service quality improvement affects revisit intentions. In order to achieve the purpose of this study, 341 visitors over the age of 19 who visited offline stores located in Busan and Gyeongnam were selected as study subjects. As a result of this study, it was found that consumers' perceived health beliefs, perceived disease infection probability, and perceived disease infection severity had a significant effect on revisit intention. In addition, it was found that the company's infection prevention information sharing and infection prevention customer management had a significant mediating effect on the relationship between perceived health beliefs and revisit intention. Based on these research results, the conclusion suggested that a company needs a series of management activities that can contribute to the sharing of information on infection prevention and customer management among members of the organization and achievement of business performance.

The service supporting structure for users in ubiquitous computing environment requires technology that divides efficiently resources shared around users according to users context. So, needs research that analyze service items and resources that is offered according to users context information and divide adaptively necessary service and resources. Therefore, in this paper we proposes an intelligent P2P mobile agent that recognizes users context using portable mobile devices and is available for intelligent service by sharing serviced item according to users' context. The proposed structure removes monopoly for specific resources, and supports effective users context-awareness and service.
