가상 현실의 궁극적인 목표중의 하나는 참여자가 가치 있는 경험을 얻을 수 있도록 하는 것이다. 경험의 내용은 순차적인 이벤트들로서 구성될 수 있으며 본 논문은 이런 이벤트들을 저작(event authoring)하기 위한 알고리듬을 개발하는 것을 목적으로 한다. Event authoring을 위해서 우리는 우선, 가상환경에 포함되는 개체들의 구조를 제안한다. 그리고, event-program을 기술하여 실험을 행할 수 있게 하는 수단인 event authoring language와 event-program 실행 시에 핵심이 되는 event execution manager를 구현한다. 마지막으로, 몇 가지 실험을 통하여 본 논문에서 제시된 접근방법이 유효함을 증명한다.

The TXS0506+056 is a blazar and counterpart of the neutrino event IceCube-170922A. It is the first time that the neutrino event and flaring event in electromagnetic wave (EM) coincided. We observed TXS0506+056 with medium-bands in optical using 0.25m and 2.1m telescope at McDonald observatory about a month after the neutrino event. We tracked the variability of SED of the target for three weeks, and our observation showed no abrupt variability in optical range during this period. We concluded that a month after the neutrino event, the TXS0506+056 became less active and shows no feature of the energetic event. We also concluded that the medium-bands are well suited for tracking SEDs of objects. Our result demonstrates the potential of the wide-field 0.25m telescope (5.5 deg^2) for finding transient objects and track the variability of sources like AGNs.

Nowadays, every kind of system is changed so complex and enormous, it is necessary to assure system reliability, product liability and safety. Fault tree analysis(FTA) is a reliability/safety design analysis technique which starts from consideration of system failure effect, referred to as “top event”, and proceeds by determining how these can be caused by single or combined lower level failures or events. So in fault tree analysis, it is important to find the combination of events which affect system failure. Minimal cut sets(MCS) and minimal path sets(MPS) are used in this process. FTA-I computer program is developed which calculates MCS and MPS in terms of Gw-Basic computer language considering Fussell's algorithm. FTA-II computer program which analyzes importance and function cost of VE consists. of five programs as follows : (l) Structural importance of basic event, (2) Structural probability importance of basic event, (3) Structural criticality importance of basic event, (4) Cost-Failure importance of basic event, (5) VE function cost analysis for importance of basic event. In this study, a method of initiation such as failure, function and cost in FTA is suggested, and especially the priority rank which is calculated by computer-aided decision analysis program developed in this study can be used in decision making determining the most important basic event under various conditions. Also the priority rank can be available for the case which selects system component in FMEA analysis.

The purpose of this study was to analyze the need for family life welfare service program, and to develope the program for managing in the Community Centers. The survey was conducted by interviewing 356 users and 360 non-users of Community Center, total 716 persons living in Daegu City, from October 8 to October 30 in 2002. The data were analyzed by the SPSS PC+ program applying t-test and ANOVA. The results were as follows : First, overall the needs for family life welfare service program, consisting of education program, facilities management and counseling program, and event program, was higher than 3.7 points. The needs level for event program was a little higher than other two programs. Second, the level of needs for family life welfare service program differed between user group and non-user group of the Community Centers. Third, the level of needs for family life welfare service program varied according to the demographic variables, such as sex, age, marital status, family life cycle, education level, vocation, monthly average income and housing type. Finally, Based on the results of needs analysis, 11 education programs, 4 facilities management and counseling programs and 5 event programs were developed for family life welfare service program. These programs developed in this study could be applied to diverse groups classified by age, social class, family life cycle of citizens. Also the programs should be applied in terms of family unit, as well as individual base to enhance the function of family life.

Many JavaScript programs are event-driven in the sense that they heavily use event functions that take user inputs to manipulate program behaviors. Thus, in order to statically analyze event-driven JavaScript programs effectively and precisely, static analyzers should be able to understand and precisely analyze the behaviors of events in terms of how they are created and evaluated. In this paper, we describe several reasons why static analysis of event behaviors in JavaScript programs is particularly difficult, and present a new event modeling mechanism that can represent behaviors of events precisely and efficiently for effective analysis of event-based JavaScript programs.

This paper designs the performance analysis layer for the various performance analysis of parallel programs using event expressions are similar to the normal program language to analyze the events which display a dynamic state exchange of a program. The event expressions suggest operations for overloading and functions which are needed in performance analysis, such as a filtering operation, data format translation functions, performance analysis, static functions, and etc. By using the event expressions, the programmer can modify the event trace data to analyze the performance and analyze more easily and variously than the pre-developed tools.

다목적위성 관제 시스템의 한 부분만 위성운용 서브시스템의 실시간 처리 성능을 분석하기 위한 알고리즘과 이를 구현한 프로그램이 개발되었다. 이 프로그램은 위성운용 서브시스템에서 발생되는 event들과 이에 대한 response들의 속성에 관한 파라미터 값이 입력되었을 때, 각 event의 반응 시간과 스케줄 가능성을 계산하고 스케줄된 event들을 시각화한다. 실험 결과, event의 blocking delay, 주기 및 첫 action의 우선 순위가 해당 event 또는 다른 event의 반응 시간에 많은 영향을 준다는 것이 밝혀졌다.

The purposes of this study are the analysis by content of satisfaction level of participants in the event for the systematic, efficient event tourism program. For this analysis, it was researched if there was any difference in satisfaction level of participants in event by demographic characteristics, participation level and content of program. The results of this analysis are as follows: There was a difference in satisfaction level by participants characteristics in the event tourism. There was the more recognition, the higher participation level. There was higher participation and satisfaction level in participational and special program than exhibitory program. This study has a limit that can"ft grasp the foreign visitors"f recognition for the event tourism in Gangnueng district. But, it is very important to analyze the voluntary participation and interest of local residents and it may be the fruit of this study to of a new program and suggestion point through the analysis of satisfaction level for the Heo-kyun & Heo_Nan_Sul_Hun Cultural Festival.

The purposes of this study were to analyze the effects of a marine leisure exhibition event(MLEE)'s appraisal attributes on visitors' satisfaction and rep-visit intention and thus provide fundamental information that facilitates developing effective marketing and operational strategies for a MLEE. In order to accomplish such purposes, this study employed a survey with a total of 300 visitors to a MLEE hosted by G Province. Questionnaires were developed on the basis of related studies and modified to reflect the study context. Then, such questionnaires were verified to be valid and reliable through content validity, factor analysis and internal consistency analysis. Valid 286 questionnaires were analyzed with correlation analysis and multiple regression analysis on significance level of .05. Following findings were derived from current study. First of all, the appraisal attributes of a MLEE had a significant effect on visitors' satisfaction and among them only the factor of event program had a unique relation with the levels of satisfaction. In addition, the appraisal attributes of the MLEE also had a significant effect on visitors' rep-visit intention behavior and among them event program, transportation and employee factors had unique relations with the performance variable in order. In conclusion, all the research hypotheses that had been set up through previous studies were confirmed in this study.
