  • Purpose: Previous studies show that perceived CSR motives have a significant impact on company evaluations. However, consumer responses to CSR motives vary depending on CSR motives. From this perspective, this study investigates the impact of CSR motives on consumers' responses in the context of food and beverage franchise companies using a scenario. Research design, data, and methodology: For achieving the purposes of the study, an example of a domestic food and beverage franchise company actively carrying out CSR activities was presented. Data was collected from 304 respondents aged 20 or older who were aware of CSR activities. The respondents answered the questionnaire after reading the scenario. The data was analyzed with SPSS 28.0 and SmartPLS 4.0 program. Result: Values-driven motive and strategic motive influence authenticity, while stakeholder-driven motive and egoistic motive did not influence authenticity. Values-driven motive influences on attitude, while stakeholder-driven motive, strategic motive and egoistic motive didn't. Lastly, authenticity influences attitude. Conclusions: Companies need to be aware that consumers may infer different motives for their CSR activities, and pay close attention to consumers' perceived motives from the planning stage of CSR activities. In particular, companies should focus on the values-driven motive and the strategic motive when planning CSR activities.

  • 이 연구는 디지털 환경에서 데이터가 중심이 되는 전자기록의 출처에 새롭게 접근하기 위해, 데이터 출처 개념과 출처 모델을 검토하고 수용하여, 어떻게 전자기록을 대상으로 새롭게 출처 개념을 적용할 수 있을지의 가능성을 살펴보았다. 이어서 데이터 중심의 전자기록을 대상으로 한 출처 표현 모델을 개발하기 위해 기초 연구를 진행하였다. 특히 소급형 출처와 전망형 출처 개념으로 전환할 것과, 기록관리 메타데이터와는 별개의 모델을 통해 출처를 표현하고 기록과 연결할 수 있는 모델을 개발할 것을 제안하였다. 기록과 동적 관계를 맺으면서도 독립적으로 출처를 표현할 수 있는 모델을 개발할 수 있다면, 오히려 기록의 유동성을 보장할 수 있으면서도, 기록의 속성과 이를 지원할 출처의 역할을 더 충실히 수행할 수 있을 것이다. 결국, 이 연구가 제안한 기본적인 모델 개발 방향을 수용하는 출처 모델은 기록의 고정성과 활동의 재현성, 재현의 신빙성을 뒷받침할 수 있을 것이며, 디지털환경에서 적합한 출처 모델로서 역할을 할 수 있을 것이다.

  • 실시간 선점형 다중 태스크 운영체제를 기반으로 구동하는 프로세서와 연결된 디바이스로부터 데이터를 입수하는 방법은 크게 폴링(Polling)과 인터럽트 구동(Interrupt driven) 방식으로 구분할 수 있다. 이들 모두에 대한 기술적인 접근은 운영체제의 스케줄링 정책 및 소프트웨어 아키텍쳐에 따라 달라질 수 있다. 위성 컴퓨팅 환경에서 위성 서브 시스템 또는 컴포넌트로부터 입수되는 데이터의 처리시 시간 준수와 정확성을 보장하는 것은 비행 소프트웨어를 개발시마다 요구되는 중요한 요구사항 중의 하나이다. 본 논문에서는 디바이스의 입출력 방식과 스케줄링과의 관계에 대한 분석 및 이에 따른 프로세서와 디바이스간의 신뢰적인 데이터 입출력 방법을 제안한다.

  • In this research, we proposed the mechanism to develop self evolving expert systems (SEES) based on data mining (DM), fuzzy neural networks (FNN), and relational database (RDB)-driven forward/backward inference engine. Most former researchers tried to develop a text-oriented knowledge base (KB) and inference engine (IE). However, thy have some limitations such as 1) automatic rule extraction, 2) manipulation of ambiguousness in knowledge, 3) expandability of knowledge base, and 4) speed of inference. To overcome these limitations, many of researchers had tried to develop an automatic knowledge extraction and refining mechanisms. As a result, the adaptability of the expert systems was improved. Nonetheless, they didn't suggest a hybrid and generalized solution to develop self-evolving expert systems. To this purpose, in this study, we propose an automatic knowledge acquisition and composite inference mechanism based on DM, FNN, and RDB-driven inference. Our proposed mechanism has five advantages empirically. First, it could extract and reduce the specific domain knowledge from incomplete database by using data mining algorithm. Second, our proposed mechanism could manipulate the ambiguousness in knowledge by using fuzzy membership functions. Third, it could construct the relational knowledge base and expand the knowledge base unlimitedly with RDBMS (relational database management systems). Fourth, our proposed hybrid data mining mechanism can reflect both association rule-based logical inference and complicate fuzzy logic. Fifth, RDB-driven forward and backward inference is faster than the traditional text-oriented inference.

  • The authors developed a nodal network model that simulates the flow of moist air and the thermal behavior of a target area. The nodal network model was enhanced using a parameter estimation technique based on the measured temperature, humidity, and schedule data. However, the nodal model is not good enough for predicting humidity of the target space, having 55.6% of CVRMSE. It is because re-evaporation effect could not be modeled due to uncertain factors in the field measurement. Hence, a data-driven model was introduced using an artificial neural network (ANN). It was found that the data-driven model is suitable for predicting the condensation compared to the nodal model satisfying ASHRAE Guideline with 3.36% of CVRMSE for temprature, relative humidity, and surface temperature on average. The model will be embedded in automated devices for real-time predictive control, to minimize the risk of surface condensation at dressroom in an apartment housing.

  • Interplanetary scintillation-driven (IPS-driven) ENLIL model was jointly developed by University of California, San Diego (UCSD) and National Aeronaucics and Space Administration/Goddard Space Flight Center (NASA/GSFC). The model has been in operation by Korean Space Weather Cetner (KSWC) since 2014. IPS-driven ENLIL model has a variety of ambient solar wind parameters and the results of the model depend on the combination of these parameters. We have conducted researches to determine the best combination of parameters to improve the performance of the IPS-driven ENLIL model. The model results with input of 1,440 combinations of parameters are compared with the Advanced Composition Explorer (ACE) observation data. In this way, the top 10 parameter sets showing best performance were determined. Finally, the characteristics of the parameter sets were analyzed and application of the results to IPS-driven ENLIL model was discussed.

  • Storage services integration can be done for achieving high availability, improving data access performance and scalability while preventing vendor lock-in. However, multiple services environment management and interoperability have become a critical issue as a result of service architectures and communication interfaces heterogeneity. Storage federation model provides the integration of multiple heterogeneous and self-sufficient storage systems with a single control point and automated decision making about data distribution. In order to integrate diverse heterogeneous storage services into a single storage pool, we are proposing a storage service federation framework named BoxBroker. Moreover, an automated decision model based on a policy-driven data distribution algorithm and a service evaluation method is proposed enabling BoxBroker to make optimal decisions. Finally, a demonstration of our proposal capabilities is presented and discussed.

  • 최근 시스템들이 복잡해지면서 시뮬레이션을 통한 시스템의 분석이 주목을 받고 있다. 시뮬레이션 분석에서 가장 핵심적인 부분 중의 하나가 시뮬레이션 모델의 검증이며, 이 과정을 통하여 시뮬레이션 모델이 얼마나 실제 시스템을 대변할 수 있는지를 판단한다. 모델의 검증에서 시뮬레이션 모델과 실제시스템의 데이터를 비교할 때 발생하는 차이는 입력 데이터의 차이에 의한 영향도 있으며, 이를 통한 모델의 검증 결과는 높은 신뢰성을 보장하지 못한다. 따라서 이 논문에서는 실제와 동일한 입력 데이터를 바탕으로 하는 Trace-Driven 시뮬레이션을 기반으로 모델을 설계하였다. 한편, 출력데이터들을 하나의 통계량을 통한 검증이 아닌 클래스 별 검증을 하기 위해 데이터마이닝 분야에서 분류기의 성능을 판단하는 F 척도를 응용하여 시뮬레이션 모델의 검증을 수행하였다. 그 결과, 제안된 검증 방법은 정밀한 모델의 검증을 가능하게 하고, 검증 시에 피드백을 제공함으로써 용이한 수정 작업을 가능하게 한다.
