일반적으로 명사구는 기본명사구와 최장명사구로 분류되는데 최장명사구에 대한 정확한 식별은 문장의 전체적인 구문구조를 파악하고 정확한 지배용언을 찾아내는데 중요한 역할을 하게 된다. 본 논문에서는 확장된 청크(chunk) 개념과 다섯 개의 클래스로 세분화된 문장부호 정보를 자질로 사용한 두 단계 최장명사구 식별 기법을 제안한다. 제안한 기법은 기본모델보다 2.65% 향상된 평균 89.66%($F_1$-measure)의 우수한 성능을 보인다.

Replication routing can greatly improve the data delivery performance by enabling multiple replicas of the same packet to be transmitted towards its destination simultaneously. It has been studied extensively recently and is now a widely accepted routing paradigm in delay tolerant networks (DTNs). However, in this field, the issue of how to maximize the utilization efficiency of limited replication quota in a resource-saving manner and therefore making replication routing to be more efficient in networks with limited resources has not received enough attention. In this paper, we propose a DTN routing protocol with back-pressure based replica distribution. Our protocol models the replica distribution problem from a resource allocation perspective and it utilizes the idea of back-pressure algorithm, which can be used for providing efficient network resource allocation for replication quota assignment among encountered nodes. Simulation results demonstrate that the proposed protocol significantly outperforms existing replication routing protocols in terms of packet delay and delivery ratio.

This paper analyses the theories and practices of the integrated management of records and archives in china which means that records and archives management departments should be interrelated each other with organic association and their records and archives be managed in an integrated manner. In 1930s chinese nationalist regime had conducted a campaign for reforming documents and archives management system to increase administrative efficiency called "The Connection of Documents and Archives Management Act(文書檔案連鎖法)". Although this campaign has not been continued to the present, It has been proved to be a quite successful attempt at that time in china and also regarded as an origin of the integrated management of records and archives in china. The practical types of the integrated management of records and archives as follows: first is to establish institutional documents/archives department in charge of managing records and archives in an integrative manner; second, to reform filing system, that is, to file on a case basis or abolish filing system and arrange records on an item level instead; third, to install software application for the integrated management of records and archives in order to make arranging operations convenient by increasing data processing efficiency. The chinese case shows us that the integrated management of records and archives could not be realized until records and archives departments make united efforts to build up a new national records and archives management system based on advanced and scientific principles.

This paper aims to simulate the isotropic elastic damage theory of Liu Jun (2012) using the self-programmed UMAT subroutine in the interface of ABAQUS. Liu Jun (2012)'s method based on the mechanic theory can not be used interactively with the currently commonly used finite element software ABAQUS. The advantage of this method in the paper is that it can interact with ABAQUS and provide a constitutive program framework that can be modified according to user need. The model retains the two scalar damage variables and the corresponding two energy dissipation mechanisms and damage criteria for considering the tensile and compressive asymmetry of concrete. Taking C45 concrete as an example, the relevant damage evolution parameters of its tensile and compressive constitutive model are given. The study demonstrates that the uniaxial tensile stress calculated by the subroutine is almost the same as the Chinese Concrete Design Specification (GB50010) before the peak stress, but ends soon after the peak stress. The stress-strain curve of uniaxial compression calculated by the subroutine is in good agreement with the peak stress in Chinese Concrete Design Specification (GB50010), but there is a certain deviation in the descending stage. In addition, this paper uses the newly compiled subroutine to simulate the shear bearing capacity of the shear key in a new structural system, namely the open-web sandwich slab. The results show that the damage constitutive subroutine has certain reliability.

In recent years, Internet Word of Mouth (IWOM) as an important way for internet consumers to obtain product information, it has become a key factor influencing consumers purchase intention. However, does IWOM also affect consumers' willingness to buy in the E-commerce live broadcast environment? What online IWOM can make a difference? And how? This study establishes a theoretical model of the impact of IWOM on consumer purchase intention in Chinese E-commerce live broadcast. Questionnaire data were collected from 204 people through the internet, with the model and the hypotheses are tested by SPSS 21.0 software. The research results show that: Firstly, the influencing factors of IWOM in the E-commerce live broadcast are different from those in general E-commerce. Secondly, anchor traits, word of mouth quantity, and product involvement have a positive impact on consumers purchase intentions, but the strength of relationship, word of mouth quality and Word of mouth timeliness do not have significantly direct effect on consumers' purchase intentions. Finally, conclusion with theoretical references and practical suggestions for E-commerce live broadcast merchants that may enter the Chinese market.

본 논문에서는 소프트웨어 정의 네트워크를 이용한 한중일 한자-한국어 변환 키워드 도메인 이름 시스템을 제안하였다. 한자 체계를 주로 사용하는 한국, 중국, 일본에서 세 나라의 한자 수량이 너무 많기 때문에 우선 한국, 중국, 일본이 공용으로 사용하는 한자 체계인 CJK808을 가지고 연구하였다. 연구를 통해 CJK808 한자 체계에서 각 나라의 한자 특징도 많이 발견하였고, 그 중에서 표준자와 이체자의 다양성이 더욱 두드러졌다. SDN을 이용함으로써 관리 측면에서 다양한 이점을 얻을 수 있다. 제안하는 시스템을 통하여 사용자들은 한국, 중국, 일본 한자를 입력하면 SDN에서 관리하는 도메인 네임 서버를 통해 IP 주소를 얻을 수 있다.

최근 소셜 플랫폼 마케팅 환경은 빠르게 변화하고 있다. 이러한 환경에서 기업은 브랜드와 서비스를 홍보하기 위해 소셜 플랫폼 인플루언서에 대한 의존도가 높아지고 있다. 이처럼 소셜 인플루언서에 대한 관심이 높아지고 있음에도 불구하고 소셜 플랫폼 인플루언서 특성이 소비자 애착과 브랜드 충성도에 미치는 영향을 탐구하는 실증적 연구는 부족한 실정이다. 이에 본 연구에서는 소셜 플랫폼 인플루언서 특성, 소비자 애착 및 브랜드 충성도 간의 관계를 살펴보았다. 중국 소비자를 대상으로 온라인 설문조사를 진행하였으며, 총 360부의 데이터를 분석에 사용하였다. 분석에는 SPSS와 AMOS 프로그램을 사용하였다. 연구 결과 소셜 플랫폼 인플루언서 특성 중 애착에 유의한 영향을 미치는 요인은 신뢰성, 전문성과 친밀성으로 나타났으며, 소셜 플랫폼 인플루언서에 대한 애착도가 높을수록 브랜드 충성도가 높아짐을 확인하였다.

Objective: The feed intake (FI) and feed efficiency are economically important traits in ducks. To obtain insight into this economically important trait, we designed an experiment based on the residual feed intake (RFI) and feed conversion ratio (FCR) of a random population Pekin duck. Methods: Two thousand and twenty pedigreed random population Pekin ducks were established from 90 males mated to 450 females in two hatches. Traits analyzed in the study were body weight at the 42th day (BW42), 15 to 42 days average daily gain (ADG), 15 to 42 days FI, 15 to 42 days FCR, and 15 to 42 days RFI to assess their genetic interrelationships. The genetic parameters for feed efficiency traits were estimated using restricted maximum likelihood (REML) methodology applied to a sire-dam model for all traits using the ASREML software. Results: Estimates heritability of BW42, ADG, FI, FCR, and RFI were 0.39, 0.38, 0.33, 0.38, and 0.41, respectively. The genetic correlation was high between RFI and FI (0.77) and moderate between RFI and FCR (0.54). The genetic correlation was high and moderate between FCR and ADG (-0.80), and between FCR and BW42 (-0.64), and between FCR and FI (0.49), respectively. Conclusion: Thus, selection on RFI was expected to improve feed efficiency, and reduce FI. Selection on RFI thus improves the feed efficiency of animals without impairing their FI and increase growth rate.
