In recent years, business environments have become more complex; therefore, enterprises must be capable of responding flexibly and agilely. For these purposes, effective enterprise systems service monitoring and early decision making based on the same, emerge as core competency of the enterprise. In addition, enterprise system techniques that filter meaningful data are needed to event processing. However, the existing study related with this is nothing but discovering of service faults by monitoring depending upon API of BPEL engine or middleware, or is nothing but processing of simple events based on low-level events. Accordingly, there would be limitations to provide useful business information. In this study, we present an extended event processing model that enables delivery of more valuable and useful business information through situation detection. Primarily, the event processing architecture in an enterprise system is proposed as a definite approach, and then define an event meta-model suitable for the proposed architecture. Based on the defined model, we propose the syntax and semantics of the elements that make up the event processing language include various and progressive event operators, the rules, complex event pattern, etc. In addition, an event context mechanism is proposed to analyze more delicate events. Finally, the effectiveness and applicability of proposed approach is presented through a case study.

Korea meteorological administration(KMA) has started to levy air meteorological service charge on both national and foreign carriers since 2005. The charge has grown on 2010 and 2014 twice. However, KMA has still kept asking airlines to agree with another increase in the charge due to the low cost of goods recovery ratio of 7%. The air meteorological charge has changed from 2,210 KRW at the beginning to 11,400 KRW as of June 2018. According to ARIMA intervention time series analysis, it was proven national carriers would make a payment of 831 million KRW 2018 and 1,024 million KRW 2019, showing 186.2% and 123.2% increase compared to last year respectively. The total amount of charge for both national LCC and foreign airlines was aggregated up to 1,952 million KRW 2019, 227% bigger than the charge paid at 2017. Considering the 50% increase of consumer price index last decade, the increased charge would impair the global competitiveness of national carriers. It could be suggested that current air meteorological charge scheme be improved to apply overseas trend and for national carriers to have a competitive advantage in global aviation market.

이동통신망에서 주파수라는 한정된 자원을 최적으로 활용하는 것은 중요한 일이며 멀티미디어 서비스를 제공하는 환경에서는 더욱 더 절실한 요소이다. 또한 이런 서비스 요구에 따라 기지국이나 단말기에서 작업 스케줄링을 어떻게 하느냐 하는 것도 전체 시스템의 성능을 평가하는 중요한 요소이다. 이동망에서 서비스 별 채널할당은 핸드오프가 일어나는 시점에 빈번히 일어나며 전체 시스템에 큰 영향을 주게 된다. 본 논문에서는 음성과 데이터 호를 동시에 서비스하는 CDMA 셀룰러 시스템에서 핸드오프를 중점으로 멀티미디어 서비스 트래픽 특성을 고려한 주파수할당과 작업 스케줄링이라는 두 가지 요소를 접목하는 방법론을 모델화하고 알고리즘을 제시한다.

This research focuses on accomplishing analysis problems and issues by examining the policies and systems related to geo-spatial big data which have recently arisen, and suggests political and systemic improvement plan for service activation. To do this, problems and probable issues concerning geo-spatial big data service activation should be analyzed through the examination of precedent studies, policies and planning, pilot projects, the current legislative situation regarding geo-spatial big data, both domestic and abroad. Therefore, eight political and systematical improvement plan proposals are suggested for geo-spatial big data service activation: legislative-related issues regarding geo-spatial big data, establishing an exclusive organization in charge of geospatial big data, setting up systems for cooperative governance, establishing subsequent systems, preparing non-identifying standards for personal information, providing measures for activating civil information, data standardization on geo-spatial big data analysis, developing analysis techniques for geo-spatial big data, etc. Consistent governmental problem-solving approaches should be required to make these suggestions effectively proceed.

The purpose of this article is to suggest using cooperative microteaching in pre-service mathematics teachers education based on their perceptions of it after actual application case. The background of this study is that cooperative learning came into the highlight as a good method to cultivate teachers' competencies for creativity and character education as well as students' creativity and character in the mathematics classroom. 20 pre-service mathematics teachers participated in their cooperative microteaching and 16 of them responded to the survey. The collected data showed that the merits of cooperative microteaching are to ease the burden of preparing for class, to discuss how to teach mathematics, to debate what lesson is better, to receive valuable feedback form their peer, and so on. Also, it provided them with the chance for self-improvement in that they kept to make up for the week points in their teaching behavior. Meanwhile, they wanted longer time to experience their teaching and their own lesson.

Metaphors, as an important way to deliver information and convince the audience, have been used in print advertising extensively. This study researches the concept of metaphors and analyses seven Chinese advertisements in which metaphors are used in public service advertising. The nature of metaphors is to express one thing by using another thing. Using metaphors can put some creative ideas into pictures and make the pictures full of visual impact. Then the target audience will pay more attention to the picture and become impressed. When people look at the advertisements using metaphors, they will definitely look up in their existing knowledge to understand the message which the advertisements are delivering. So this makes the advertisements more attractive and the people would be more easily convinced.

When we assign frequency resources to a new radio service, the existing services need not to be interfered with by the new service. Therefore, when we make a frequency assignment, a guard band is necessary to separate adjacent frequency bands so that both can transmit simultaneously without interfering with each other. In this paper, we propose an efficient frequency guard band decision rule for avoiding interference between radio services. The guard band is established based on the probability of interference in the previously arranged scenario. The interference probability is calculated using the spectrum engineering advanced Monte Carlo(MC) analysis tool(SEAMCAT). After applying the proposed algorithm to set up the frequency guard band, we can decide on the guard band appropriately because the result satisfies the predefined criterion.

Recent demands of market forces are causing considerable attention to be forced on logistics functions and revitalizing interest in outsourcing them. The need to efficiently and economically adjust support to meet market demands is growing significantly. Logistics is playing a role it has never played before. In light of this, outsourcing to third parties has become a strategic issue demanding greater attention in corporate boardrooms. From the perspective of TPL users, this paper focuses on how best to make a strategic plan for the effective utilization of TPL. And the results are as follows : First, after deciding their logistics outsourcing, the companies have to set up the aim of TPL through development of logistical strategies. Second, the companies must decide service provider that fits to their business environment and conditions. Third, they have to conclude a contract with logistics service provider. Fourth, after doing the preparatory implementation they carry into effect the original implementation. Fifth, they use the result of original implementation to fix a partnership.

There become more people suffering from cancer, so the number of cancer patients are increasing as well. However, cancer patients should go through a lot of psychological and physical stress because of side effects of drugs, especially alopecia, during the treatments for cancer. Especially female patients relatively more take care of their appearance, therefore it imposes much more psychological stress for them. Most of the patients choose wig as an alternative, but it is difficult for them to choose right wigs because of their lack of knowledge about wigs. Wigs not only make up for the bald hair but helps asthetically if patients choose right wig which goes well with their face, and eventually helps patients have self-esteem and makes them be positive in their social activities. The purpose of this research to offer right data and qualitative aid about wig, so that it can enhance the quality of cancer patients' lives.
