Recently, as the sensor and big data analysis technology have been developed, there have been a lot of researches that analyze the purchase-related data such as the trajectory information and the stay time. Such purchase-related data is usefully used for the purchase pattern prediction and the purchase time prediction. Because it is difficult to find periodic patterns in large-scale human data, it is necessary to look at actual data sets, find various feature patterns, and then apply a machine learning algorithm appropriate to the pattern and purpose. Although existing papers have been used to analyze data using various machine learning methods, there is a lack of statistical analysis such as finding feature patterns before applying the machine learning algorithm. Therefore, we analyze the purchasing data of Songjeong Maeil Market, which is a data gathering place, and finds some characteristic patterns through statistical data analysis. Based on the results of 1, we derive meaningful conclusions by applying the machine learning algorithm and present future research directions. Through the data analysis, it was confirmed that the number of visits was different according to the regional characteristics around Songjeong Maeil Market, and the distribution of time spent by consumers could be grasped.

The purpose of this study was analyzing the Transforming Characteristics of the Entrance of Privately-built Apartment housing in Daegu from the 1970s to the 2000s. First of all, this study made an investigation into the general situation of Privately-built Apartment housing and the general idea of the Entrance. Through a field study, This study was analyzing change of an era of entrance of Apartment housing till quite recently existing in Daegu. The results are as the body III follows. Results of the research through change of an era is as follows. The change tendency is not to be big before 2003, but It has under gone change after 2003. Studies show that It is the care for the old and the weak, to take interest in natural lighting, to be going to change from passing the time of space to staying space and more space, to show interest in the preservation of public peace and design. So, The Entrance of Apartment housing has a bias towards more elegant. This research look forward to having an intention of furnishing preliminary data for a residence environment of high quality.

The concept of variable is a big idea to develop algebraic thinking. Variable has multiple meanings such as the unknown, a tool for generalization, and the relationship between varying quantities. In this study we analyzed in what ways the meanings of variable were presented in the current elementary mathematics textbooks and workbooks. The results showed that the most frequent meaning of variable was 'the unknown', 'a tool for generalization', and 'the relationship between varying quantities' in order. A close look at the results revealed that the same symbol was often used in representing different values of variable as the unknown. In taking variable as a tool for generalization, questions to provoke generalization were sometimes included not in the textbooks but in the teachers' manuals. The main focus in dealing with variable as the relationship between varying quantities was on finding out the dependent values compared to the independent ones. Building on these results, this study is expected to suggest implications for how to deal with variable concept in elementary mathematics instructional materials.

This study intends to look through the development of female costume during the 100 years after the flowering time. By refocusing on the flow the Korean female costume, this study present representative costume style of that time and find out the fashion cycles. For this purpose, the clothes during the 100 years (from 1890 to 1993) were observed and changes of female costume, hair style and shoes were observed. Literature review and content analysis method used. The results of this study are as follows : For Korean costume, there were little changes in basic styles and only the jacket and skirt lengths were changed. After 1960s, as modernization of socio-cultural aspects were processed, Korean costume became formalized and structure of costume was duplicated. In the 1960's mint skirts and pantalons won popularity. In the 1970's , diverse modes including mini, midi, maxi, pantalon, hot pants appeared, and especially the jeans were popular. In the 1980's big & loose silhouette was in fashion in the beginning, and fit & flare silhouette later in the decade. In the 1990's styles emphasizing natural feminity came in fashion. In addition, by analyzing the development of female costume styles of Korea, Fashion cycles were found, expecially in the phenomenon of 70's styles repeating in the 90's.

GTX(Great Train Express), the wide area express train of a big city center of metropolitan area, is the best new transportation method able to realize 'Low Carbon Green Growth' for solving traffic congestion of the metropolitan area with the connection the metropolitan area into 40-minute life zone by speeding up the standardized velocity, making the route straight and reducing the compensation of land using the space of 40~50m below the ground. In the transportation sector all over the world, if it turned into the public transportation system focusing on the train at a point of time that low carbon green revolution takes the initiative, national competitiveness would be enhanced by reducing the emission of carbon from cars by 1/6. Accordingly, this study is to look into the efficient operation in accordance with GTX construction superintended by currently Gyeonggi province and to consider the optimum operation plan of GTX that are proper for the actual circumstances of the country by comparatively analyzing overseas cases that took their positions as new transportation by curtailment of transit time through highspeed such as London area, Paris area, and Tokyo area etc that are similar to Korean metropolitan area.

While industrial development as many buildings were builted, amount of energy consume in building also increase rapidly. At this point be tormented the energy depletions are big problem on the rise. The development of renewable energy in trying to resolve the fundamental problem that the technical level is still incomplete. Because of this, reduce energy use in buildings to lot of study. Most of the energy involved in building mechanical system for so many research is continue. Among them, be interested in building mechanical system. Building mechanical system is configured Air conditioning, sanitation, urban (environmental) equipment. In the design of equipment, installation, maintenance, applies to all devices in the field of industrial equipment and general engineering equipment field are within bounds to say that all of the equipment field. However, domestic technology level is still fly short of international standards in architecture, we spand many energy. Because of this, find the current situation and identify the problems look up ways to improve them.

The purpose of this paper is to study characters' make-up coordination that changes the narrative of the fantasy movies to a visual fantasy, especially it focuses on the post-modern features from the works of Tim Burton, a post-modernist. The contents of the study are, firstly, studying post-modernism that influenced the works of Tim Burton, secondly, researching (1988), (1989), (1990), (1992), (2003) and (2005) and their main characters' make-up design. Thirdly, analyzing the otherness and plural-code that are the post-modern characteristics expressed on characters' make-up coordination of fantasy movies. The otherness means the division of the middle and the surroundings and the rise of the outsiders. Fantasy characters that scares off human such as ghosts, aliens, apes, kidults, mutations, man-made men are in the middle. The plural-code takes the symbolic and pluralistic dimension in to the movie, mixes the sign system, and which natural and supernatural system cross over. In the movies, Beetle Juice who was both ghost and devil expresses life and death, Bat man, Cat woman, Penguin man expresses human and animal, and Edward means human and inhuman. Willy Wonka's makeup makes him look younger, but his grown-up-like clothes show doubleness. For that matter, make-up coordination is the mirror of reflection of period and human being's inner life.
