다중작업학습(Multi-Task Learning, MTL) 기법은 하나의 신경망을 통해 다양한 작업을 동시에 수행하고 각 작업 간에 상호적으로 영향을 미치면서 학습하는 방식을 말한다. 본 연구에서는 전통문화 말뭉치를 직접 구축 및 학습데이터로 활용하여 다중작업학습 기법을 적용한 개체명 인식 모델에 대해 성능 비교 분석을 진행한다. 학습 과정에서 각각의 품사 태깅(Part-of-Speech tagging, POS-tagging) 과 개체명 인식(Named Entity Recognition, NER) 학습 파라미터에 대해 Bi-LSTM 계층을 통과시킨 후 각각의 Bi-LSTM을 계층을 통해 최종적으로 두 loss의 joint loss를 구한다. 결과적으로, Bi-LSTM 모델을 활용하여 단일 Bi-LSTM 모델보다 MTL 기법을 적용한 모델에서 1.1%~4.6%의 성능 향상이 있음을 보인다.

본 연구는 치위생(학)과 학생들에게 보다 나은 임상실습교육을 제공하기 위해 학제와 재학특성에 따른 임상실습 만족을 파악하고, 임상실습 업무별 만족이 전반적인 임상실습 만족도에 미치는 영향을 분석하였다. 연구대상은 임상실습 경험이 있는 강원도 소재의 K 대학(279명)과 경기도 소재의 K 대학(154명)을 편의추출 하였다. 임상실습에 대한 치위생(학)과 학생들의 전반적인 만족도는 학제, 재학특성, 임상실습 내용별 만족, 임상실습 업무별 만족에 따라 차이가 있었다. 또한, 임상실습 업무별 만족도는 임상실습 전반적 만족도에 영향을 주는 것으로 나타났다. 이에 체계적인 실습교육을 제공하기 위한 실습 내용과 방법의 적절성을 확보하는 등의 적극적인 노력이 요구되며, 임상실습 만족도에 대한 지속적인 후속연구가 필요할 것이다.

In this example, a message passing based multicomputer system with general interdonnedtion network is considered. After multicomputer systems are developed with morm-hole routing network, topologies of interconecting network are not major considertion for process management and resource sharing. Tehre is an independeent operating system kernel oneach node. It communicates with other kernels using message passingmechanism. Based on this architecture, the problem is how mech does performance degradation will occur in the case of processor sharing on multicomputer systems. Processor sharing between application programs is veryimprotant decision on system performance. In almost cases, application programs running on massively parallel computer systems are not so much user-interactive. Thus, the main performance index is system throughput. Each application program has various communication patterns. and the sharing of processors causes serious performance degradation in hte worst case such that one processor is shared by two processes and another processes are waiting the messages from those processes. As a result, considering this problem is improtant since it gives the reason whether the system allows processor sharingor not. Input data has many parameters in this simulation . It contains the number of threads per task , communication patterns between threads, data generation and also defects in random inupt data. Many parallel aplication programs has its specific communication patterns, and there are computation and communication phases. Therefore, this phase informatin cannot be obtained random input data. If we get trace data from some real applications. we can simulate the problem more realistic . On the other hand, simualtion results will be waseteful unless sufficient trace data with varisous communication patterns is gathered. In this project , random input data are used for simulation . Only controllable data are the number of threads of each task and mapping strategy. First, each task runs independently. After that , each task shres one and more processors with other tasks. As more processors are shared , there will be performance degradation . Form this degradation rate , we can know the overhead of processor sharing . Process scheduling policy can affects the results of simulation . For process scheduling, priority queue and FIFO queue are implemented to support round-robin scheduling and priority scheduling.

기술의 발달과 스마트 스피커 보급의 증가에도, 스마트 스피커의 대화 오류로 사용자 만족도는 하락하고 있다. 이 연구는 스마트 스피커의 대화형 에이전트 맥락에서 '자기발화수정 전략'이 과업 중요도 수준과 대화 오류 여부에 따라 사용자 경험에 미치는 영향을 살펴보았다. 대화 오류에 따라 시나리오를 제작하고 과업 중요도 수준에 따라 집단을 나눠 실험을 진행해 신뢰, 지각된 유용성, 지각된 용이성, 수용의도를 측정하였다. 연구 결과, 에이전트의 자기발화수정 전략은 완전한 수행과 비교해 신뢰와 지각된 용이성에 부적 영향을 주며, 과업 중요도와의 상호작용을 통해 수용의도에 영향을 미치는 것을 발견하였다. 이 연구는 대화형 에이전트 연구에서 미흡했던 자기발화수정 전략의 효과를 실증적으로 알아보았고, 자기발화수정 전략의 수용과 관련된 사용자 경험 요인을 살펴보았다는 점에서 의의를 가진다.

Role-Based Access Control(RBAC) is a flexible and policy-neutral access control technology. But, for large systems, managing roles, users, permissions and their interrelationships is a formidable task that cannot be centralized in a small team of security administrators. Using RBAC to manage RBAC provides addition히 administrative convenience. In this paper we demonstrate the implementation of one of the components of ARBAC99 which deals with permission-role assignment and is called PRA99. We implement it by using EJB component and use Oracle stored procedures to implement it.

There is an emergence of Internet applications that have real-time requirements. These applications require IP to support guaranteed capacity, higher priority and lower packet loss rate. To address this, the Internet Engineering Task Force (IETF) is developing a set of protocols and standards for Integrated Services on the Internet. Using RSVP and policies to manage the allocation of network resources in order to provide different levels of service is a topic of great interest to service providers. Currently, it is not possible to dynamically reallocate resources during an application's session. This paper discusses how policies in conjunction with new service class can provide a more enhanced network resource allocation by allowing for this dynamic reallocation.

As Electronic Commerce is getting larger, the volume of Internet-based commerce by enterprise is also getting larger. This phenomenon applies to Internet EDI, Global Internet Business, and CALS information services. In this paper, a new type of cryptographic key recovery mechanism satisfying requirements of business environment is proposed. It is also applied to enterprise information infrastructure for managing employees' task related to handling official properties of electronic enterprise documents exchange. This technology needs to be complied to information management policy of a certain enterprise environment because behavior of cryptographic key recovery can cause interruption of the employees' privacy. However, the cryptographic key recovery mechanism is able to applied to any kind of information service, the application areas of key recovery technology must be seriously considered as not disturbing user's privacy It will depend on the policy of enterprise information management of a specific company.

The purpose of this study was to examine the realities of physical health conditions of children aged from 0 to 11 for the last decade. On the basis of the analyzed results, the pragmatic and policy issues are as follows : First, in the perspective of child development, studies of physical health are needed for the benefit of integrative development of children. Second, appropriate health education programs suitable for ages of children need to be developed and made compulsory for them. Third, the prohibition of adopting the ranking evaluation in physical education is to be required at the policy level. Forth, for sustainment of the health-related activities for children, the space or facilities specifically prepared for families to exercise and rest are needed. Lastly, new regulations and management systems are needed in order to resolve the safety problems with food for children.

Recently, the interdisciplinary linkage between engineering and social science has received an increasing attention as an emerging education discipline. Due to intrinsic complexity of innovation process and heterogeneity of disciplinary nature, however there exists little, if not no, effort to draw a common framework in terms of educational scope and contents of the new subject. This paper presents a number of criteria and guidelines for building up new educational framework by integrating engineering subject and social science subject. Specifically, three neo-disciplines, technology policy, technology management, and economics of technology are considered since it is postulated that the forementioned disciplines have established academic identity and fundamental structure By nature, this paper is an exploratory and seminal one. It is not the purpose of this paper to provide a concrete table of contents of educational material. Instead, it merely brings up a discussion topic for the wide audience of academic arena, leaving the gradual consensus and convergence as future task.
