The purpose of this study was to examine attitude of cultural events that affect participation satisfaction and loyalty of cultural events. Although cultural events are increasingly important with its positive impact on event participants, the existing literature on cultural event is sparse. This study, thus, investigates moderating effects of cultural events' involvement in a relationship between attitude of cultural event and participations' satisfaction and loyalty to understand the thoughts and attitude of participants. The survey was undertaken of participants to cultural events in Seoul, resulting in 513 valid responses. Through statistical analyses of factor analysis, multiple regression and hierarchical regression, four different factors of cultural event attitude were identified and those factors affect participation satisfaction and loyalty of cultural events. The results of this study provided support that there were moderated effects of cultural event involvement in the relationships between cultural event attitude and satisfaction and loyalty. More theoretical and practical implication were discussed in the conclusion.

With the proliferation of advanced wireless network and sensor technologies, smart devices under USN(ubiquitous sensor network) environment are capable of collecting context information such as temperature, humidity, weight, and location about objects at real time. Therefore, applications must be able to analyze collected information and notify useful information to wanted users timely. This service can be realized by implementing an event-based middleware. In the middleware, event messages collected from physical environment will be filtered according to profiles that users define in advance and the result will be sent to the interested users. In this paper, we present XML-based event model, ECA-based profile model, and the architecture of an event-based middleware suitable to USN environment. We will also model and describe them using the examples of logistics area. By implementing the system based on the design above, the middleware enable applications or users to easily access to physical sources. The proposed middleware can also apply to not only logistics area but also other various areas under USN environment such as intelligent traffic control system, national disaster management system and u-medical system.

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.

Since high packet losses occur in multi-hop transmission of wireless sensor networks, reliable data transmission is required. Especially, in case of event-driven data, a loss recovery mechanism should be provided for lost packets. Because retransmission for lost packets is requested to a node that caches the packets, the caching node should maintains all of data for transmission in its buffer. However, nodes of wireless sensor networks have limited resources. Thus, both a loss recovery mechanism and a buffer management technique are provided for reliable data transmission in wireless sensor networks. In this paper, we propose a buffer management technique at a caching position determined by a loss recovery mechanism. The caching position of data is determined according to desirable reliability for the data. In addition, we validate the performance of the proposed method through computer simulations.

This study aims to clarify the effect of forest management practices(thinning and pruning) on water quality to get the fundamental information on the facility of cleansing water quality after forest operation. Rainfall, throughfall and stemflow were sampled at the study sites which consist of Abies holophylla and Pinus koraiensis in Kwangnung Experimental Forest for 6 months from May 4, to November 1, 1999. Average tree height in the management sites increased by 0.5m more than that in the non-management sites in Abies holophylla and Pinus koraiensis, respectively. Increment of average D.B.H. at the management sites grew 3.5cm and 2.6cm more in Abies holophylla and Pinus koraiensis compared with that at non-management sites. Average pH of the total amount for the event in throughfall and stemflow was higher than that of throughfall and stemflow of the beginning of the event at the management and non-management sites. Average electrical conductivity of throughfall and stemflow at the beginning of the event was higher than that of the total amount for the event at management and non-management sites. Water qualities of throughfall and stemflow were buffered more by the management practice in both. The forest management may affect purification of water quality of throughfall and stemflow in Abies holophylla and Pinus koraiensis.

High performance sensors and modern data logging technology with real-time telemetry facilitate system fault diagnosis in a very precise manner. Fault detection, isolation and identification in fault diagnosis systems are typical steps to analyze the root cause of failures. This systematic failure analysis provides not only useful clues to rectify the abnormal behaviors of a system, but also key information to redesign the current system for retrofit. The main barriers to effective failure analysis are: (i) the gathered data (event) logs are too large in general, and further (ii) they usually contain noise and redundant data that make precise analysis difficult. This paper therefore applies suitable pre-processing techniques to data reduction and feature extraction, and then converts the reduced data log into a new format of event sequence information. Finally the event sequence information is decoded to investigate the correlation between specific event patterns and various system faults. The efficiency of the developed pre-filtering procedure is examined with a terminal box data log of a marine diesel engine.

US Retailers consider two major holiday shopping days as their most profitable-the Friday after Thanksgiving, Black Friday, and the Monday after Thanksgiving, CyberMonday. Online shopping discount events have boosted up the shopping markets resulting in pumping up National economy. For such reasons, Korea also has launched online shopping discount event, which is called 'Cyber hot days'. The primary purpose of this paper is to understand consumer behavior on Cyber hot days and suggest how retailers can harness those consumer behaviors and how government agency can support both retailers and consumers to boost up shopping markets. The results of empirical test shows that economic value, emotional value, and product variety were found to be significantly related to consumers' attitude on Cyber hot days, but convenience value, social value, and product uniqueness were not. Consumers' attitude was also found to be significantly related to the repurchase intention. It implicates that price, enjoyment, and product variety are important aspects to Korean consumers when they purchase during online shopping discount event.
