Data mining technique is used to find hidden knowledge by massive data, unexpectedly pattern, relation to new rule. The methods of data mining are decision tree, association rules, clustering, neural network and so on. Clustering is the process of grouping the data into clusters so that objects within a cluster have high similarity in comparison to one another. It has been widely used in many applications, such that pattern analysis or recognition, data analysis, image processing, market research on off-line or on-line and so on. We analyze Gyeongnam social indicator survey data by 2001 using twostep clustering technique for environment information. The twostep clustering is classified as a partitional clustering method. We can apply these twostep clustering outputs to environmental preservation and improvement.

However, western-originated cultural perspectives brought the strong self-devaluated view on their own cultures to both countries. And that's the first cause of substitution of western clothings for ordinary ones in both nations.

In the area of hotel and tourism sector, various research are analyzed using big data. Big data is being generated by any digital devices around us all the times. All the digital process and social media exchange produces the big data. In this paper, we analyzed the de-identification method of big data to use the personal information of hotel guests. Through the analysis of these big data, hotel can provide differentiated and diverse services to hotel guests and can improve the service and support the marketing of hotels. If the hotel wants to use the information of the guest, the private data should be de-identified. There are several de-identification methods of personal information such as pseudonymisation, aggregation, data reduction, data suppression and data masking. Using the comparison of these methods, the pseudonymisation is discriminated to the suitable methods for the analysis of information for the hotel guest. Also, among the pseudonymisation methods, the t-closeness was analyzed to the secure and efficient method for the de-identification of personal information in hotel.

Architecture is a kind of culture and has advanced in the wooden architecture with a considerable change. The study investigated a phylogenetic relationship between two countries based on characteristics of architectural universality. With comparison and analysis on the common feature and difference of the beam and structure in the wooden architecture from the Koryo and Zhejiang Province(China), the systemicity of the wooden architecture was examined. The beam is a part of timber which is consist of the wooden structure frame and also a crucial subject to understand a development process of the wooden architecture.

The satisfaction of wearing an outfit in daily life can lead to the attitude toward the clothes and further the brand image and repeat purchases; however, satisfaction generated from the moment the outfit was purchased is only temporary. Therefore, it would be necessary to study the antecedent variables that precede daily outfit satisfaction. In the current study, to understand the antecedent variables that influence the daily outfit satisfaction of consumers, in-depth interviews were conducted on thirteen women in their 20s and 30s. The results showed that peoples' outfit satisfaction was dependent on a comparison between their prior expectation and the performance of the outfit based on expectation-performance disconfirmation. The outfit performance was evaluated by themselves or others. Simultaneously, it was found that the others' opinion on the clothes and surroundings influence daily outfit satisfaction. This research helps deepen the understanding on the individual and social influential factors of the temporary satisfaction from purchase to the satisfaction of actually using clothes. This result ultimately intensifies the understanding on the consumption and evaluation of clothes in the whole life cycle of clothing products from purchase to disposal.

This research focused on the priotity decision for establishment sriteria on the effects which environmental sculptures in urban area. The analysis performed in this study used the AHP(Analytic Hierarchy Process) that is recognized as a useful decision-making tool to select and evaluate alternatives through pairwise comparison in the context of hierarchical decision structure. The results obtained from the analysis drawn by collecting the professional opinions of 5 experts for environmental sculptures are as follows: 1. The orders of establish criteria priorities on environmental sculptures were harmony of environment> symbol> public> function. The harmony of environment was the most important priority because it showed the highest weight of criteria. 2. The alternative priorities of environmental sculptures were the meaning of work>setting place> social contribution> physical quality .The meaning of work showed the highest change in the weight of alternative. 3.The sensitivity analysis of environmental sculptures demonstrated that the rate of change in the alternative priorities of the public was stabilized although the criteria importance varied, while the harmony of environment, the symbol intimated and function of priorities has their rates of weight changed if the criteria priorities were high.

In order to achieve the goals, it was analyzed the similarities and differences on the contents of "100 The beautiful sounds of Korea - 1999" and "100 Soundscapes of Japan - 1996" in view of the intents of selection, the process of selection, and the construction of the results. The result show that there are the both similarities and differences on the intent and the process of selection, types and extent of sound samples, interactions among human-sound environment-region, the identities of the regions as well as the recognized sound environment. Also, the result shows that it is very important to preserve ecological, social, and cultural sound environment of the region. In order to practice this ideology of soundscape in Korea, there is a necessity for converting people's consciousness and participating voluntary residents' movement.
