Purpose: The purpose was to analyze the effects of internal marketing activity factors on nurse's turnover intention, nursing task performance and nursing productivity. Methods: The subjects were 355 nurses who were working at the 3 universities hospital over 1 year. The instruments were used of internal marketing activity factors(Lee, 2001), turnover intension(Lee, 1995), nursing task performance(Park, 1988) and nursing productivity(McNeese-Smith, 1996). Results: The mean score of internal marketing activity factors was 2.79, education and training 2.97, individualization 2.93, communication 2.87, promotion 2.76, work environment 2.63, reward system 2.62, and management vision for employee 2.61. The turnover intention was 3.12, nursing task performance 3.49, and nursing productivity 3.38. The internal marketing activity factors were negatively correlated with turnover intention(r=-0.37, p<0.0001), and positively correlated with nursing task performance(r=0.29, p<0.0001) and nursing productivity(r=0.30, p<0.0001). The key predictor of turnover intension was reward system, education and training, communication, and salary. They explained 35.0% of the total variance. In nursing task performance, communication, management vision for employee, salary and unit explained 26.0% of the total variance. In nursing productivity, communication, reward, education and training, salary, and position explained 24.0%. Conclusions: To increase nurse's nursing task performance and nursing productivity and to decrease turnover intention, it is necessary to concentrate on improving communication and reward system in the internal marketing activity factors. Through these activities, the effectiveness of internal marketing strategies will be enhanced and finally, nursing organizational outcome will be increased.

Purpose : This study examines The impact of human resource investment in internal control on stock price crash risk. Effective internal control ensures that information provided is complete and accurate, financial statements are reliable. By overseeing management, internal control systems can reduce agency costs between management and outside parties. In Korea, firms have to disclose information about internal control systems. The working experience of human resources in internal control systems is also provided for interested parties. If a firm hires more experienced internal control personnel, it can better facilitate the disclosure of information. Prior studies reported that information asymmetry between managers and investors increases future stock price crash risk. Therefore, the longer working experience internal control personnel have, the lower probability stock crashes have. Research design, data and methodology : This study analyzed the association between the working experience of internal control personnel and crash risk using regression analysis on KOSPI listed companies for fiscal years 2016 through 2017. The sample consists of 1,034 firm-years of non-financial firms whose fiscal year end on December 31. Career spanning data of internal control personnel was collected from internal control reports. The professionalism(IC_EXP) was measured as the logarithm of the average working experience of internal control personnel in months. Negative conditional skewness(NSKEW) and down-to-up volatility (DUVOL) are used to measure firm-specific crash risk. Both measures are based on firm-specific weekly returns derived from the expanded market model. Results : We find that work experience in internal control environment is negatively related to stock price crashes. Specifically, skewness(NSKEW) and volatility (DUVOL) are reduced when firms have longer tenure of human resources in internal control division. The results imply that firms with experienced internal control personnel are less likely to experience stock price crashes. Conclusions : Stock price crashes occur when investors realize that stock prices have been inflated due to information asymmetry. There is a learning effect when internal control processes are done repetitively. Thus, firms with more experienced internal control personnel could manage their internal control more effectively. The results of this study suggest that firms could decrease information asymmetry by investing in human resources for their internal control system.

내연기관은 연료로 공급되는 에너지의 30~40%만을 동력에너지로 전환되고 나머지 60~70%는 손실에너지와 배기에너지로 버려지게 된다. 따라서 배기에너지를 회수한다면 기계적 에너지 또는 전기적 에너지로 변환시킬 수 있다. 열전발전기는 배기관에 위치하여 고온 열원과 저온 열원 사이에 온도차를 이용한다. 두 열원 사이에 온도차를 이용하여 전기적 에너지를 발생시켜 동력 에너지 등 여러 에너지로 변환 가능하다. 이 논문에서는 이러한 열전발전기의 특성을 예측하기 위해 수치해석을 통하여 여러 조건에 따른 열전발전기 특성을 예측하였다. 수치해석 결과 고온 열원과 저온 열원 간의 온도 차이가 클수록 발생하는 전력 역시 증가하는 것을 알 수 있었다.

The DEVS(discrete event system specificaition) formalism specifies a discrete event system in a hierarchical, modular form. DEVSIM++ is a C++based general purpose DEVS abstract simulator which can simulate systems modeled by the DEVS formalism in a sequential environment. This paper describes P-DEVSIM++which is a parallel version of DEVSIM++ . In P-DEVSIM++, the external and internal event of DEVS models can by processed in parallel. For such processing, we propose a parallel, distributed optimistic simulation algorithm based on the Time Warp approach. However, the proposed algorithm localizes the rollback of a model within itself, not possible in the standard Time Warp approach. An advantage of such localization is that the simulation time may be reduced. To evaluate its performance, we simulate a single bus multiprocessor architecture system with an external common memory. Simulation result shows that significant speedup is made possible with our algorithm in a parallel environment.

임베디드 소프트웨어는 대상 시스템의 내부 자원과 호스트 시스템의 환경에 매우 민감하므로 수행시 대상 시스템과 동일한 환경에서 디버깅해야 한다. 그러나 대상 시스템의 자원에 직접적으로 접근하여 시스템 상태를 조사하거나 제어하는 기법들은 내부 신호나 자원에 대한 접근이 제한되어 있는 SoC (System-On-a-Chip) 소프트웨어를 디버깅하기는 부적합하다. 본 논문에서는 JTAG을 기반으로 원격 시스템에 접근하여 임베디드 소프트웨어를 디버깅할 수 있는 어뎁터를 제안한다. 이는 원격 디버깅을 위한 환경 구축에 많은 어려움 있는 기존의 환경 구축의 경제적 제한점을 해소할 수 있다. 따라서 본 논문은 원격 시스템내의 임베디드 소프트웨어를 디버깅할 수 있는 경제적인 인터페이싱 환경을 제공한다.
