This study aims to examine the structural relationships of the consumers' understanding on the event, product satisfaction, promotional strategies, and behavioral intention in a promotional event for agricultural senary industry. The study conducted a survey among the participants in promotional events. The result showed that the understanding of promotional event had a positive effect on consumer behavioral intention, which means that the greater the understanding of The senary industry and the purpose of the event, the greater the consumer behavioral intention. The consumer satisfaction on products also had a positive effect on consumer behavioral intention, implying that the consumer behavioral intention increased when their satisfaction in terms of the taste and price of the products is higher. Further, the higher the satisfaction of the promotional strategy, the higher the consumer behavioral intention. Lastly, the promotional strategy played a mediating role between the consumer's understanding of the event and the satisfaction of the product, and the consumer behavioral intention. The result suggests that the different promotional strategies including discounts, freebies, or free-samples are able to maximize the effect of promotional events through its mediating effect.

The future is complex and unpredictable. In particular, it is unlikely to occur, but once it occurs, no one knows how it will affect our society if X-event, which has a tremendous impact, is created. This study was conducted only in the climate field to offset the ripple effect of this X-event, and was conducted through in-depth interviews with experts from the Korea Army Research Center for Future & Innovation and the Army College. As a result, it was possible to explore what factors would trigger X-event from their discourse and what X-event would be newly created by spreading them to other fields. Starting with this study, if we accumulate the discourse of experts in various fields such as population, science and technology, as well as climate, and other fields other than the Army, we can predict X-event and offset the threats that may arise.

최근의 경쟁적 비즈니스 환경은 각 기업으로 하여금 민첩성과 유연성을 요구하게 되었고, 이를 위하여 기업에서 제공하는 서비스에 대한 실시간 모니터링과 이를 통한 조기 의사 결정이 기업의 핵심 경쟁력이 되었다. 또한, 엔터프라이즈 시스템에서 발생하는 수 없이 많은 다양한 이벤트들을 효과적으로 처리하기 위하여 의미 있는 데이터를 필터링 할 수 있는 기술이 요구되고 있다. 하지만, 이와 관련된 기존의 연구는 BPEL엔진이나 미들웨어의 API에 의존한 모니터링으로 서비스 결함 발견에 그치고 있거나 낮은 단계의 이벤트(low-level event)에 기반한 단순 이벤트 처리에 그치고 있어, 기업에 유용한 비즈니스 정보를 제공하기에는 한계가 있다. 본 논문에서는 다중 상황 검출(situation detection)을 통해 보다 가치 있고 유용한 비즈니스 정보의 제공을 가능하게 하는 확장된 복합 이벤트 모델(complex event model)을 제시한다. 구체적으로, 먼저 엔터프라이즈 시스템에서의 이벤트 처리 아키텍처를 제안하고, 제안된 아키텍처에 적합한 이벤트 메타모델을 정의한다. 정의된 메타모델을 기초로 다양하고 진보된 이벤트 연산자와 복합 이벤트 패턴, 그리고 키(key) 등 이벤트 처리 언어를 구성하는 요소의 문법과 의미를 제안한다. 또한, 보다 정교한 이벤트 분석을 위한 이벤트 컨텍스트 매커니즘을 제안한다. 마지막으로 응용사례를 통하여 본 연구의 적용 가능성을 보여주고, 다른 이벤트 모델과의 비교를 통해 본 이벤트 모델의 장점을 제시한다.

This study focused on comparing the meteorological conditions in the Atmospheric Boundary Layer (ABL) on high-event days and non-event days in the Seoul Metropolitan Area (SMA). We utilized observed PM10 and meteorological variables at the surface as well as at the upper heights. The results showed that high-event days were consistently associated with lower wind speed, whereas wind direction showed no particular difference between high-event and non-event days with frequent westerlies and northwesterlies for both cases. During high-event days, the temperature was much warmer than the monthly normal values with a sharp increasing trend, and Relative Humidity (RH) was higher than the monthly normal, especially on high-event days in February. During high-event days in spring, a double inversion layer was present at surface and upper heights. This indicates that stability in the multi-layer is an important indicator of higher PM10 concentrations. Net radiation in spring and winter is also closely associated with higher PM10 concentrations. Strong net radiation resulted in large sensible heat, which in turn facilitated a deeper mixing height with diluted PM10 concentrations; in contrast, PM10 concentrations were higher when sensible heat in spring and winter was very low. We also confirmed that convective and friction velocity was higher on non-event days than on high-event days, and this was especially obvious in spring and winter. This indicated that thermal turbulence was dominant in spring, whereas in winter, mechanical turbulence was dominant over the SMA.

This study is to test the influence of stock option granting information on the firm's performance. The important issue in stock option is that agent cost is the important determinant factor for the long term performance. The agent cost arises between the manager and shareholders. So many study are concentrated in diminishing the agent cost, and develop some substitute tools to measure the agent cost. The event study about stock option analyzes returns around event date at a time. Event study provides estimation periods and cumulative returns. Announcements about stock option are generally associated with positive abnormal returns in short term period, but not showing positive effect in long term period. It is important to investigate the responses of stocks to new information contained in the announcements of stock option. Therefore it is important to study the long term performance in the case of stock option. The event time portfolio approach exists the CAR model, BHAR model and WR model. And the calendar time portfolio approach has the 3 factor model, 4 factor model, CTAR model, and RATS model. This study is forced to develop and arrange two approach method in evaluating the performance, the event time portfolio approach and calendar time portfolio approach.

Appreciating the aspect of modem architecture requires not only the comprehension of the nature of design and architects' ways of thinking and expression but also observers' views on buildings and their perceptive/cognitive stages. This calls for an in-depth study on the "system of phenomenological perceptions" that works as a new architectural experience system. The system of phenomenological perceptions makes it possible to specify the individual process of understanding architecture, that is, hands-on experiences, participations, feelings, perceptions, and cognition. The value of user experience and cognition has been emphasized by philosophical and aesthetical concepts as well. Therefore, in order to better appreciate the modern architecture, this study suggests theoretical consideration to "orientation and event" that are crucial elements in understanding a phenomenological view and materializing actual space formation. This offers the cognitive system with which we analyze modem architecture and comprehensive expressional methods. In other words, this study contemplates the system of phenomenological perceptions from an existential spatial perspective by structurizing the system of the orientation and the event in order to segmentalize users' current locations, potential directions, the relations with spaces, continual vie'wpoints as well as buildings' functions and interior and exterior division. The system of phenomenological perceptions helps understand and systemize modern architecture through a system based on relations between sensation, perception, cognition, sensitivity, and rationality. This creates a new cognitive system employing the concept of the orientation and the event, which is different from a normal cognitive system basing on the sense of vision. When observers appreciate space, they tend to relate the space to a certain event and to remember their experiences in it. During the process, they draw borders of the space in which the event takes place and give shape to their experiences including actions, movements, cognition and sensation. The process leads to the formation of "placeness," and here, the concept of the orientation comes in as the location and the center of the placeness. This study proves that a determined orientation coupled with individual experience and events settles the place ness; detailed elements in the cognitive system have close relations with one another; the orientation, actions, events, and places are the factors that materialize observers' architectural experience.

Owing to the convergence of the communication network with the control system and public network, security threats, such as information leakage and falsification, have become possible through various routes. If we examine closely at the security type of the current control system, the operation of the security system focuses on the threats made from outside to inside, so the study on the detection system of the security threats conducted by insiders is inadequate. Thus, this study, based on "Spotting the Adversary with Windows Event Log Monitoring," published by the National Security Agency, found that event logs can be utilized for the detection and maneuver of threats conducted by insiders, by analyzing the validity of detecting insider threats to the control system with the list of important event logs.

A heavy foggy event accompanying with complex coastal fog was investigated in this study. This heavy foggy event occurred on FEB 11, 2015. Due to reduced visibility with this foggy event induced more than 100times serial traffic accidents over the Young-jong highway, and Flights from 04:30 AM to 10:00 AM were cancelled on Inchon International Airport. This heavy foggy event was occurred in synoptic and mesoscale environments but dense coastal fog were combined with a combination of sea fog, steam fog, and radiation fog. This kind of coastal fog can predicted by accurate analysis of the direction of the air flow, sea surface temperature(SST), and 925hPa isotherms from numerical weather prediction charts and real time analysis charts.
