본 논문은 CORBA, Ice 등의 다른 미들웨어들과 비교하여 성능, 품질, 사용자 편의성 등에서 높은 평가를 받고 있는 공개 메시지 지향 미들웨어인 ZeroMQ 기반의 다중 에이전트 메시지 전송 구조를 제안한다. 제안 구조는 FIPA 에이전트 표준 규격들로부터 MTS(Message Transfer System) 등의 개념들을 빌려와 사용하고 있으며, 다중 에이전트 플랫폼 SMAF(Smart Multi-Agent Framework)의 구조적 장점을 계승한다. 제안 구조는 ZeroMQ 커뮤니티에 알려져 있지 않은 새로운 방식의 피어 대 피어 구조를 사용한다. 제안 구조는 MTS 마다 단 하나의 라우터 소켓만을 사용하여 MTS들 간의 피어 대 피어 통신을 지원한다. 제안 구조는 ZeroMQ가 지원하는 다양한 장치들과 패턴들에 대한 호환성과 확장성을 가지며, 전통적인 분산 에이전트 응용 분야들 뿐 아니라 에이전트들 간의 밀접한 협력을 필요로 하는 지능형 로봇과 같은 분야도 지원할 수 있다.

Under the four-cut system, low-lignin alfalfa (Medicago sativa L.) may extend harvesting intervals improving harvest management flexibility and producing forage products with higher nutritive values. The objective of this study was to compare forage yield and nutritive values of low-lignin and conventional alfalfa varieties when applied to six different harvest schedules in the first (2016) and second (2017) production years. There were 12 treatments of two alfalfa varieties as whole plots and six harvest schedules as subplots. Across harvest schedules, there were four cuttings in two production years. Three harvest intervals including "Standard" (high quality, HQ), "Standard+5-day" (medium quality, MQ), and "Standard+10-day" (high yield, HY) were chosen for the first cutting, and 30-day (HQ) and 35-day (HY) for the second cuttings. The third and fourth cuttings in 2016 were timed near final harvest date and in 2017 occurred at 35-day (MQ) and 40-day (HY). Variety by harvest schedule interaction was not significant, but the whole plot and sub-plot effects were significant. Hi-Gest 360 was consistently higher in nutritive value and with a similar yield as Gunner. Harvest schedules did not consistently differ in forage yield and nutritive values. HS-1 ("Standard" + 35-day + Medium Quality + High Yield) with shorter first two cutting intervals provided lower acid detergent fiber (ADF), neutral detergent fiber (NDF), higher relative feed value (RFV), and similar forage yield compared to other schedules. HS-1 had the highest economic incomes when considering RFV and yield among the six different harvest schedules.

Purpose: To reinforce the product competitiveness of Korean small and medium-sized business in the world market. Methods: By clarifying the definition of a masterpiece, developing global masterpiece quality index(MQI) equipped with checklists, surveying several companies and customers, and analyzing the results of the survey via the MQ zone diagram. Results: The results of the survey show the gap between Korean small and medium-sized business and global masterpiece companies in terms of MQI. From this analysis, in order for the surveyed Korean companies to be the world-class ones, the managerial aspects to be improved could be clearly pointed out through the measurement indices. Conclusion: This research would provide Korean small and medium-sized companies, which wish to get on the global masterpiece level, with an objective guideline.

Nowadays many countries in the world have been implementing TQM which is originated from Japanese management style. There are many research results that TQM has a positive influences on business results. But the levels of implementing TQM are different by countries. The domestic competitors and the customers, who have the great influences on business results are also quite different. Therefore the levels of TQM in some company and the influences of TQM factors on business results are supposed to be different by countries. The situations of the countries lying on the more developed stage will be a good benchmarks for the countries on following stages. There are few researches on this cross countries analysis. This paper do the empirical study on the effects of TQM factors on business results between Korean and Japanese small or medium sized manufacturing companies. First, the levels of TQM are compared between countries. Second, what key success factors among TQM ones are for business success is analyzed for each country and compared between two countries. This study will help to plan the road maps in TQM journey for the Korean companies.
