This study identified the important service quality of the emerging night market as an alternative for the revitalization of the traditional market. This study also was to analyze the effects of service quality on customers' emotions, behavior intention and local performance in night market, and to provide an effective operation plan. The collected data were analyzed by frequency analysis, factor analysis, reliability analysis and multiple regression analysis using SPSS 16.0 Version, a statistical package program, and various results were discovered. First, all the service quality factors (convenience, food, event program, physical environment) had a positive (+) effect on positive emotion, and the service quality factors except event program had a negative (-) effect on negative emotions. Second, the service quality factors had a partially positive (+) effect on behavior intention and local performance. Third, the positive and negative emotions had a effect on behavior intention, however, the positive emotions had a positive (+) effect on local performance. Consequently, the present study confirmed that service quality in the night market is important factors for emotions, behavior intention, and local performance. Therefore, the findings of this study is capable of being the basic data for revitalizing the traditional market in the future.

Waveforms of $CO_2$ gas shielded arc welding in short circuit transfer mode was studied with the waveform analysis program, which can calculate various waveform factors such as number of short circuit event, mean and standard deviation of short circuit time and arc time. The calculated values of these factors were correlated independently or in combination with the spatter generation rate to figure out the most reliable index for evaluating spatter generation and further for arc stability. As a result this study, it was confirmed that the spatter generation tends to decrease with the increase of short circuit frequency. Further to this, it was also found that as the short circuit frequency increases the short circuit event becomes more uniform resulting in the decrease of standard deviations ($\sigma$values) of short circuit time and arc time. This result demonstrated that these factors are strongly correlated with each other and thus any one of these factors can be used for the evaluation index. In the discussion, however, short circuit frequency was proposed for the most practical index in evaluating the arc stability of short circuit transfer mode since it is the one which could be monitored in-process condition without any complex caculation process.

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.

This study explores the effectiveness and applications of event collection programs, which are integrated programs with event experience and collection experience as a cooperation model that combines school education and library resources as course-related materials. For the purpose, a triangulated analysis with both quantitative and qualitative data was conducted. As a result, This study examined an event collection program's effectiveness which were positive effects on the participated students' reading and perceptions on the roles of their school libraries. The event collection supported the students to self-construct their knowledge by exploring information with the provision of a collection with various materials on a topic, which would be hardly provided within the traditional library subject classification, and that the event collection program could be a useful tool for self-directed reading due to its promotion of interaction, sharing, and participation among materials and the participated students by functional factors of experiential marketing.

With the huge success of Social Network Services, studies on social network analysis to extract the current issues or to track the symptoms of epidemic disease are being carried out actively. On Twitter, tweets reflect people's reaction to an event and users' individual status well, so it is possible to detect an event regarding a tweet as a sensory value. Recently, social signals are used to detect the spread of illness like the flu as well as the occurrence of disaster event like an earthquake in early stages. In this paper, we set up a cold as a target event and regarded tweets as Cold Signals. To evaluate the reliability of Cold Signals, we analyzed correlations between weather factors and the cold index provided by Korea Meteorological Administration.

The purpose of this study is to examine customer behavior when choosing event menu at the banquet restaurant of a five-star hotel and analyze the factors of choosing the menu and its customer satisfaction. Based on the results of this study, it is possible for hotel mangers to develop good banquet event menu choices and use them when changing menu. This study adopts the Enter Method, and "t" defines 3 variables such as physiological intent, quality of food, and reasonable price. However, the other factors such as sensory images of food, contents of menu, promotion menu, cleanliness and services prove not to be important variables in this study. Among most important 3 variables, quality of food with the highest figure($\beta$ .416) is the most important variable to customer satisfaction followed by physiological intent ($\beta$ .283) and resonable price($\beta$ .134).

Concurrency control is one of the important factors to maintain consistent conditions of a game because most participants of the game should be shared information to play the game through a distributed network system. replay delay times should establish in every event and the received event should be saved and performed simultaneously for Concurrency Control. However, it is not easy to practice the event with same speed in environment having various moving speed. Therefore, expansion have to be provided. In other words, one of the most important factors of a game's efficiency is the process of bandwidth and delay. the process of concurrency control method based on scalable prediction for Multi-platform games would minimize the loss rate of a event and then would improve the interaction capacity of a game. It also might get reliability between clients. This paper analyzes some problems in terms of a layout of a game that integrates a cable and a wireless system. In addition, this paper provides methods to expand bandwidth and delay that might be an obstacle of a On-line game and to ensure reliability between a server and a client.
