As the importance of big data analysis increases to improve the competitiveness of a corporate, a unified big data project development methodology is required in order to study the problem of a corporate in a systematic way and evaluate the problem w.r.t. a business value after solving the problem. This paper propose Scientific Data Anslysis and Development methodology(SDAD) which are integrated methodology of software development and project management for easier application into a field project. SDAD consisits of 6 stages(problem definition stage, data preparation stage, model design stage, model development stage, result extraction stage, service development state), each stages has detailed processes(47) and productions(93). SDAD, furthermore, unified previous ISP, DW, SW development methodologies in terms of the data analysis and can easily interchange the productions with them. This paper, lastly, introduces a way to assign responsible persons for each process and provide communication procedures in RACI chart to improves the efficiency of the interaction among professionals from different subjects. SDAD is applied to a Bigdata project in Korea Employment Information Services institution and the result turned out to be acceptable when evaluated by the supervision.

Mitologia is about visualizing relations of information in user-oriented method. Most information given in life has invisible relations with each other. By analyzing the common characters and relations of information, we can not only measure the importance of the information but also grasp the overall properties of the information. Especially human relations are the major concerns of social network having several visualization methodologies shown by analyzing relations of each individual in society. We applied social network theory to grasp relationships between characters in Greek mythology representing a limited society. But the current tools of social network analysis have limits that they show the information one-sided way because of the ignorance of user-oriented design. Mitologia attempts to suggest the visual structure model more effective and easy to understand in analyzing data. We extracted connections among myth characters by evaluating classes, frequencies of appearance and emotional links they have. And we raised the understanding of users with furnishing the proper interaction to the information. The initial interface offers 4 kinds of indexes helping to access character nodes easily, while zoom-in function can be used for the detailed relations. The Zoom-in is quite different from usual filtering methods. It makes the irrelative information invisible so that users can find out the characters' relation more easily and quickly. This project suggests the layout to show overall information relationships and the appropriate interactions to present detailed information at the same time.

Recently, structural health monitoring system(SHMS) has been appled cable bridges as the effective maintenance tool and the management threshold is considered to assess the status of the bridge in SHMS. The threshold is generally determined by the allowable limit based on design specification because there is no method and standard for threshold calculation. In case of the conventional thresholds, it is difficult to recognize the event, abnormal behavior and gradual damage within the threshold. Therefore, this study reviewed the problem of previous methods and proposed the advanced methodologies based on probabilistic approach for threshold calculation which can be applied to practice work. Gumbel distribution is adopted in order to calculate the threshold for caution and warning states considering the expectations for return periods of 50 and 100 years. The thresholds were individually determined for measurement data and data variation to detect the various abnormal behaviors within allowable range. Finally, it has confirmed that the thresholds by the proposed method is detectable the abnormal behavior of real-time measuring data from SHMS.

Purpose - This study examined marketing communication in traditional markets by assessing consumers demonstrating brand loyalty through repeat purchases despite active marketing by competing brands hence, showing that the brand did not lose customers owing to communication. Specifically, this study examined the effects of marketing communication factors in traditional markets upon consumers' store loyalty and to determine consumers' practical and hedonic values, as moderating variables. Moreover, this study determined that both experienced and inexperienced consumers in traditional markets could similarly assess the market and examined the outcome of traditional market development as well as future strategies. Research design, data, methodology - To verify the relationship between marketing communication and store loyalty, and the moderating effects of shopping value, data were collected from 230 consumers in the Gyeonggi Province to test the theoretical model and its hypotheses. Although the field of distribution management typically uses two research methodologies, this study was conducted using empirical methodology. Specifically, analysis of variance and hierarchical regression analysis were used to test the hypotheses. Results - Consumers who had experienced the traditional market placed a greater emphasis on the physical environment or word-of-mouth marketing. Moreover, other factors apart from advertising had a significantly positive influence upon marketing communication sub-factors and store loyalty. Word-of-mouth marketing was found to be more important than other factors, therefore affirmative word-of-mouth marketing was considered important from various viewpoints. The study investigated the moderating effects of hedonic value and practical use value in the relationship between marketing communication sub-factors and store loyalty: The negative influence of publicity, physical environment, and word-of-mouth marketing was considered to be statistically significant. Conclusions - Consumers who made use of the traditional market did not think of the physical environment in an affirmative way, and consumers who did not make use of the traditional market perceived it as having a poor physical environment. However, consumers who engaged in word-of-mouth marketing experienced the traditional market in an affirmative way. Consumers who made use of the traditional market had significantly high hedonic value and/or practical use value, therefore future strategies should encourage consumers to make more use of the traditional market. Consumers who had experienced the traditional market demonstrated strong market loyalty. For consumers who did not make use of the traditional market, marketing communication was likely to influence store loyalty in a different manner from a practical perspective. In other words, marketing communication was needed to develop the traditional market, and consumers who did not make use of the traditional market should be given the opportunity to do so. Consumers having low hedonic values experienced high publicity to have high store loyalty, and consumers who experienced good facilities of the traditional market had high store loyalty (Nam & Jun, 2011). Consumers with low hedonic values as well as those with high hedonic values on the traditional market could have high store loyalty through affirmative word-of-mouth marketing.Therefore, various types of events and strategies were needed to enable consumers to experience the traditional market in an affirmative way.

Cities will soon host two third of the population worldwide, and already today 80% of the world energy is used in the 20 largest cities. Urban areas create 80% of the greenhouse gas emission, so we should take care that urban areas are smart and sustainable as implementations have especially here the greatest impact. Smart Cities (SC) or Smart Sustainable Cities (SSC) are the actual concepts that describe methodologies how cities can handle the high density of citizens, efficiency of energy use, better quality of life indicators, high attractiveness for foreign investments, high attractiveness for people from abroad and many other critical improvements in a shifting environment. But if we talk about Entrepreneurship Ecosystem and Innovation, we do not see a lot of literature covering this topic within those SC/SSC concepts. It seems that 'Smart' implies that all is embedded, or isn't it properly covered as brick stone of SC/SSC concepts, as they are handled in another 'responsibility silo', meaning that the policy implementation of a Science and Technology Park (STP) is handled in another governing body than SC/SSC developments. If this is true, we will obviously miss a lot of synergy effects and economies of scale effects. Effects that we could have in case we stop the siloed approaches of STPs by following a more holistic concept of a Smart Sustainable City, covering also a continuous flow of innovation into the city, without necessarily always depend on large corporate SSC solutions. We try to argue that every SSC should integrate SP/STP concepts or better their features and services into their methodology. The very limited interconnectivity between these concepts within the governance models limits opportunities and performance in both systems. Redesigning the architecture of the governance models and accepting that we have to design a system-of-systems would support the possible technology flow for smart city technologies, it could support testbed functionalities and the public-private partnership approach with embedded business models. The challenge is of course in complex governance and integration, as we often face siloed approaches. But real SSC are smart as they are connecting all those unconnected siloes of stakeholders and technologies that are not yet interoperable. We should not necessarily follow anymore old greenfield approaches neither in SSCs nor in SP and STP concepts from the '80s that don't fit anymore, being replaced by holistic sustainability concepts that we have to implement in any new or revised SSC concepts. There are new demands for each SP/STP being in or close to an SC/SCC as they have a continuous demand for feeding the technology base and the application layer and should also act as testbeds. In our understanding, a big part of STP inputs and outputs are still needed, but in a revised and extended format. We know that most of the SC/STP studies claim the impact is still far from understood and often debated, therefore we must transform the concepts where SC/STPs are not own 'cities', but where they act as technology source and testbed for industry and new SSC business models, being part of the SC/STP concept and governance from the beginning.

With its history of two thousand years of studying the human mind, Confucianism may be applied to contemporary emotional science for its unique perspectives and methodologies in understanding the origin of the human mind. By examining the Confucian understanding of human mind according to general Confucian ideas as well as the scholar, LEE Whang's, an idea similar to contemporary 'emotion' in Confucianism was discovered. Importance of the sentiment was not in the resulting goodness originating from one's fundamental nature, but rather its goodness was only achieved when human nature manifested itself without any distortion. This good emotion, namely 'sensibility', presents the essential difference Confucian understanding bears in comparison to the contemporary concept. And the system for grasping the human mind was considered to be the viewpoint of examining the contents and subject of function than a formal system of functioning human mind. It assumes the stance of looking into thehuman mind from the general and synthetic view of contemporary cognitive, emotional, biological and philosophical perspectives. Overall, the researchconcludes that there existed a long history of high-level research into the human mind in Confucianism that may satisfactorily provide partial reference and understanding as well as consequent perspectives and knowledge for discovering the common denominator with the emotional science.

Numerous past studies have shown that safety and serviceability of many concrete infrastructures and buildings built in 1970's have far less strength capacities than their original intended design capacities, thereby requiring repair and strengthening. Currently, aged concrete structures are being repaired using various methods developed in the past. Unfortunately, these methods do not consider the specific conditions that these members are under, but they merely attach repairing materials on the external surface for random strength improvements. Therefore, in order to improve repair and strengthening methods by considering composite behavior between repairing material and structural member, enhanced construction methodologies are needed. Also, the enhanced repairing and strengthening methods must be able to be implemented on structural members constructed using high performance concrete to meet the present construction demand of building mammoth structures. Therefore, in this study, a repairing and strengthening method for retrofitting high strength concrete (HSC) columns that can effectively improve column performance is developed. A square HSC column's cross-sectional shape is converted to an octagonal shape by attaching precast members on the surface of the column. Then, the octagonal column surface is surface wrapped using Carbon Fiber Sheets (CFS). The method allows maximum usage of confinement effect from externally jacketing CFS to improve strength and ductility of repaired HSC columns. The research results are discussed in detail.

Recently as the user experience's importance has been emphasized, there has been many tries of various research methodology in order to understand the user. Specially, as the political investigation method's user understanding method based on the statistical analysis so far has encountered a limit, there has been a continuous tendency to try to introduce a humanitarian or cultural anthropological methodology. As part of this effort, there has been many tries of various approach methods of the Ethnography which is the cultural anthropological typical research methodology, but among those the Diary Study Method is mentioned as one of the effective methodologies. Therefore this thesis applies the Diary Study Method to the notebook PC bundle SW's attitude research and tries a deep rooted research about the user attitude. Also centered to the project of understanding the notebook PC bundle SW's user receptivity. it shows a specific example of the Diary Study applied to the user understanding. Through this process, we will examine the summary about the Ethnography research method, and will discuss an effective research methodology by through the process of analyzing and deducting the user inclination by applying and designing the Diary Study to the project. That is to say, it was progressed by actually applying the research methodology through a specific case, with the purpose of breaking away from the textbook discussion and progress with an application aspect discussion. Through the current research, we will verify an active user-inclined process about the user's notebook PC SW, and it is expected to be useful in establishing a SW UX strategy and distribution related to the bundle software.

Purpose - This study examines the adverse press coverage that has increased in proportion to the remarkable growth of various kinds of franchise businesses in the food service industry. Today, the trust of franchisees in relation to their franchisor, and the maintenance of good relations between the two, has become a significant social issue. This study investigates relationship satisfaction and the long-term commitment between the franchisor and franchisee. Research design, data, methodology - We used a path analysis to investigate the relationship between justice and trust, trust and relationship satisfaction, justice and relationship satisfaction, trust and long-term commitment, and relationship satisfaction and long-term commitment. Structural Equation Modeling and a Sobel test were used to investigate the mediating effects of trust and relationship satisfaction. Data were collected from 237 Food Franchisees in Seoul and Gyeonggi Province in order to test the theoretical model and its hypotheses. Two research methodologies are generally used in the distribution management field. For this study, an empirical method was used. Results - A causal analysis was carried out to test if the research model has a sufficient fit index (for instance, χ² = 46.694, df = 10, p = .000, GFI = 0.946, AGFI = 0.850, RMR = 0.034, NFI = 0.966, CFI = 0.973), and the results showed that the model was sufficient, thus demonstrating the suitability of the research model. Each hypothesis had a positive influence, both on long-term commitment and relationship satisfaction. Justice with the franchisor had a positive influence on trust. Relation satisfaction cognized by franchisees was found to positively influence long-term commitment. The franchisee perception of justice in relation to the franchisor had no significant influence on long-term commitment. The study investigated the hypothesis that trust could mediate justice and long-term commitment, and that relationship satisfaction could also mediate long-term commitment Both trust and relationship satisfaction were found to be important for long-term commitment. Specifically, trust sub-factors and justice sub-factors influenced long-term commitment. Identification-based and knowledge-based trust were more important than calculus-based trust. Distributive justice was deemed more important than procedural justice; distributive justice should thus be strengthened. Conclusions - Both franchisor and franchisee were independent businesses. Evidently however, the franchisor could not ensure profit without long-term commitment from the franchisee. As for the success of the franchise business, the franchisor should carry out appropriate strategies leading to a satisfactory relationship. For example, transparency makes it possible to maintain and enhance trust and to improve relationship satisfaction. Just relations between franchisor and franchisee should make it possible to maintain and enhance the franchisee's trust. The franchisor should provide a variety of information with respect to the franchisee's business success. Finally, in order to improve the franchisee's long-term commitment, the franchisor should ensure a just approach with trust and relationship satisfaction among their strategies.

Weathered foliation could act as a critical failure plane because this type of plane tend to have low roughness and long extensions. A big constructed slope at $\bigcirc\bigcirc$ road construction site was failed due to the block movement along a fault zone which is parallel to foliation. Tectonic activity reactivated a fault zone parallel to foliation, and the fault clay within the shear zone metamorphosed retrogressively to chrolite. The failed block moved when the block weigh lost the balancing with the resisting force of the retrogressively metamorphosed chrolite. Evaluating the three dimensional distribution of the foliation was critical for establishing a plan for the stabilization of the slope. For this purpose, 10 boreholes were drilled as a lattice distribution, and the BIPS analyses are performed at each boreholes. The fractures measured in the boreholes are projected into 15 cross sections and their distributions are analysed, using Fracjection software. The projection analyse show that the strike of the foliation gets dipper towards left side of the slope. This geometry indicates that there are more failure block geometry at left side of the slope. Potential failure planes are searched using the projection method, and these information are provided for further support design.
